I've heard so many horror stories of women who wait until their mid-thirties or later to have children, then find out that they are infertile. I'm 25 years old now and nowhere near getting married or having babies, yet I don't want this to happen to me when I'm ready. What can I do now to protect my fertility and make sure I am able to conceive when the time is right? It's causing me a lot of anxiety!!

1) I have seen multiple advertisements for egg donation in my school's newspaper. I could sell my eggs for $25,000 or more! That's a year of tuition! There's got to be a catch. When I do some research to find out the procedure and the risks, I only seem to find oocyte donation "businesses" — not the most straight forward sources on the subject. Alice, I trust you! Can you tell me... what have I got to lose?

2) I see lots of ads in the paper here at my school about egg donors wanted. I think that I would like to donate an egg, but I can't find any information on the net about donating — only about receiving a donation. Can you tell me what the process is like, how long it takes, and whether there are side effects or permanent long-term effects? Or point me towards some other resource.

My girlfriend and I have oral sex. I heard that if you blow in the vagina of a female that it could kill her. Is that true?

I've noticed when I get highly sexually aroused, my fingers get numb, and so do my lips. Is this normal?

I've been on birth control pills for eight years and I'm thinking about trying a few months off them. They were prescribed when I was pretty young because of very irregular periods. I also was involved in a monogamous relationship for a number of years, so they were convenient. Now I have no steady partner, and am really curious to see how I feel without taking these pills. Would it be ok to go off them at the end of my pill pack or should I consult someone at health services first? If I go off for a few months and my periods are as horrendous as they were when I was younger, would it be safe to start up again on my own (I usually just see someone once per year for pill checks)?

Why does it take millions of ejaculated sperm to fertilize one egg?

1) It seems that I can't maintain an erection for more than a couple of minutes during intercourse. In fact, sometimes it doesn't seem to want to get up and play at all. The girlfriend is really starting to take this personally, but I know it's not her fault. Help! Are there any vitamins, diets, etc. that may help?

2) To put it very simply, I am having trouble having erections for a while now. I used to be able to. I can't have them at all, during intimate encounters or during masturbation. I get a little "hard" but cannot get completely hard. Could you please help me? Thank you!!

My period is late this month, and I'm afraid that I may be pregnant. The weird thing is, though, my partner and I never actually had actual sexual intercourse (in other words, there was no penetration). I'm wondering if the wet environment could still be a risk. I'm hoping that it's due to stress and fatigue with finals coming on that causing this delay. How long should I wait before getting tested?

I have been on the Nuvaring for three months now, and I am keeping it in for the four weeks then changing it because my doctor said there's no need for me to have a period. About two weeks ago I started having dark brown discharge and it has gotten more heavy, but only when I run or stand up real quick. Is this normal or should I call my doctor and find out what is going on?

My roommate and I were wondering whether or not there was a difference in sleeping with a man with an uncircumcised penis or one that has been cut? My roommate's current boyfriend is uncircumcised and she has heard horror stories about sleeping with men that have uncircumcised penises.

I seem to feel more strongly sexed (hornier) than usual during my menses and so do some of my girlfriends. Is there a clinical explanation for that or are we just weird?

I have had a notebook (laptop) computer for three years now. I never use it on a desk, but rather surf the web with it sitting on my lap. Since I am only 18 years old, I worry that someday I may try to make a baby and fail. Could an electronic device such as this sitting above my testicles every day lead to infertility?

Is it possible for nonpregnant women or women who have never been pregnant to lactate? If so, what would be the best way to stimulate in a safe, healthy way? I'd love to please my new husband with this. Are there any draw backs?

My friend had to have both of his testicles removed because of Testicular Torsion... will he be able to get an erection now?? What are the testicles for, anyway??

Is it possible to have too much sex? I didn't see any content on nymphomania. Could you please explain it? Is it considered a disease or something? I'm beginning to think it's a bad thing having too much sex, but it's difficult to consider giving it up; just a mini vacation seems forever and this is for both of us!

I have recently been advised that my on-going migraines might be caused and/or increased by the use of contraceptives containing estrogen. To that end, I have been recommended to switch to a progesterone-only form of birth control. Which, in turn, basically means I get to choose between Implanon and Mirena (I really can't stand needles, so Depo is out for me!). I am only 23 years old, and have not yet started a family. I do want to have children someday, and am very enticed by the idea of Mirena lasting to the point when I might want to begin trying to get pregnant. However, all of the advertisements for Mirena state that ideal candidates have already had children.

Is Mirena still safe for use in women who have not yet given birth? If so are there any additional side effects to consider in this instance?

I am not sure who the father of my son is. Is it possible to tell the father of the baby simply by knowing blood types and Rh factors of myself and the potential fathers?

My wife and I had our first child last July. Until about 3 months ago, she was unable to reach orgasm at all. Of late, she has very small one's, but they don't seem to be getting much better. Prior to having the baby, she had strong, very quick (3-5 minutes) orgasms 90% of the time. I know the stress of being at work rather than home with the baby could play a part in this. Is this common and is there a way to mitigate the problem? 

If one has a long-term partner and neither AIDS nor any other STD is a concern, is there any medical reason not to perform cunnilingus on a menstruating woman? My significant other is particularly horny during her period and would love cunnilingus at this time. I am willing but curious.

I'm a 19-year-old female. I had my right ovary removed (oophorectomy) three years ago due to a very large ovarian cyst. I was assured by my gynecologist that I'm still capable of bearing children but wasn't informed thoroughly of all of the pros and cons in regards to this type of operation (e.g., can the estrogen loss have any negative physical affects?). If you could shed some light on this matter, it would be greatly appreciated. Thanks.

First, I'd like to thank you for this service! It's been so informative to read the advice you've given others. I'm a female grad student and have just gotten into a relationship for the first time. I have a few questions regarding oral sex: my boyfriend loves to suck my nipples and I feel great when he's doing it, but after a while, my nipples start to feel tender and actually hurt sometimes... is this normal? He's not rough when he's doing it, so I'm not sure why this happens.

Also, when my boyfriend "goes down" on me, I worry about what he thinks of my smell and taste. He says he likes it, but I can't be sure... is there some way of finding out if my scent is normal? Can he pass any infections (to my vagina) from his saliva? (He has had only 1 one-night stand affair and he used a condom that time).

Also, I masturbate him (I stroke his penis) until he "comes," but I'm afraid of tasting his "come." He hasn't asked me to, but I think he would like it if I did... how can I overcome this inhibition? Are there any risks for me? I appreciate any help/advice... Thanks a lot!

I'm wondering if washing immediately and throughly after intercourse helps prevent pregnancy.

I was just wondering about the difference in effectiveness between "ultra sensitive" and regular condoms. I imagine there is a greater chance of breakage with thin condoms, right? Sorry if this is a silly question, but for some reason, I thought I heard that there wasn't a significant difference.

I have encountered a problem I never expected; my boyfriend is quite simply very large. I am unable to perform oral sex except for the first couple of inches due to the girth, and vaginal sex is not totally satisfying for him because he is too long and cannot fully penetrate without causing me significant pain. I've seen my doctor, and am reassured that there is physically nothing wrong with me — no infections or scarring, but am finding it difficult to come up with a solution. Any suggestions?

I once read an article stating the soy products (espcially soy milk) can lead to impotence within males if taken to a high degree. I go through random bouts in my life where I cut out cow milk completely and drink just soy milk for long periods of time (not because I'm lactose intolerant but for argued health benefits). I'm just wondering whether drinking strictly soy milk every day (at least 3 10-oz. glasses for me) is overkill.

I have been having this problem where my period will not stop. My period is usually not regular — I won't have one for about two months and then I will have one for about a-month-and-half, but this time it is hasn't stopped for three months now. What do you think I should do? I would really love to know what is wrong.

1) Could you give me some information about frigidity?

2) What is "sexual apathy" exactly?

This might sound like a gross question, but I do need an answer! When my partner performs oral sex on me, I'm not sure if my vagina is moist because I'm wet or because I have vaginal discharge... which is what? Isn't it normal for a woman's vagina to be somewhat moist, and to have a little discharge? When a woman gets wet, how can she tell? And know the difference between that and discharge?

Also, my partner and I haven't tried intercourse yet (I am a virgin)... I've read your previous answer to a man who said his penis might be too big for his partner; I am worried that I'm too small/tight for my partner. It doesn't look easy for him to even enter, and I don't know how I can make my opening wider to accommodate him (how much foreplay, how long?). How much pain does the woman feel? Thanks a lot!!

I recently saw a flyer in one of the public restrooms at my college claiming that tampons contained harmful synthetic fibers that can cause cancer. Is this true?

Is it possible to get pregnant when I am a lactating mother of a three month old baby and I missed my period this month? Last month, I had spotting — like I have periods for two days for the first week and second week of the month. I’m worried about getting pregnant again. Please help me; we had sex two days after my spotting/period.

1) I have never had sex, but I have tried now twice with my boyfriend, and it has been incredibly painful. It felt like there was a barrier inside me, and the second time I bled. I feel like I am relaxed, and my boyfriend is very gentle and slow, but it still really hurts — more than I think it should. I am able to use tampons — I'm not that small — but I don't know what the problem is. Is it supposed to hurt this much? Could there be something wrong?

2) I'm a virgin, and the first time my boyfriend inserted his fingers in my vagina, it hurt a lot, and I got sore down there. I didn't reach an orgasm, but faked it so he would stop. I didn't enjoy it at all and I was wondering... is this going to happen when I have sex? Is it going to be as disappointing?

I have two questions, first: On my birth control pill box instructions it says to take a pill each day at ABOUT the same time. I was wondering, does this mean that I should set an alarm to make sure I take it the exact minute every day (which is what I've been doing) or can I take it within a couple of hours difference if I decide to sleep in on Saturday?

Secondly: My doctor told me that if I miss a pill to consider myself unprotected for that month. However, after I left I realized that in biology class we learned that a ovum (or egg) can only survive a few days inside the fallopian tubes and uterus and then it get absorbed into the body (or dies). If I missed a pill then wouldn't I only be unprotected for the next couple of days (if an egg was produced in the 24 hr period that I didn't take the pill) instead of the whole month?

Do you and your husband both have to orgasm in order to get pregnant?

Today my partner and I were having sex and he "released" himself inside me. After sex, he began using a dildo on me until I was satisfied. Well, after going in and out of me real hard and fast, a foam-like substance began to appear. The foam was exactly like hair mousse. I am not on any type of birth control (he has a vasectomy), and I was recently tested for STDs a couple of months ago and everything was fine. Could you please tell me what this may have been from!
