Are the preservatives in saline solution safe for your eyes?

As an avid contact wearer, I use saline solution to rinse my contacts daily before each use. Recently, a friend told me that many commercial saline solutions contain preservatives, which could affect the overall health of my eye. Is this something I should be concerned about? The saline I use has always felt comfortable so I never thought it could pose a problem.


Can I decrease the amount of sleep I need?

Is there any way that I can reduce the amount of sleep I need voluntarily? Right now, I need a lot of sleep (ten hours or more) and I would like to reduce this so that I can sleep healthily for eight hours a night. Is this possible, given the way that my body works? I have heard that it is, that I can "train" my body to require less sleep. It certainly isn't healthy to sleep fewer than eight hours if my body needs ten, of course. And I'm sure that some people are forced to sleep for six or fewer hours a night for years! Do their bodies just adapt?


What's normal when it comes to wet dreams?

1) Are wet dreams in a sexually active 23-year-old male unusual?

2) I only had about three to four "wet dreams" in my entire life and now I'm 20 years old. I wonder if it is normal, or it's because I masturbate often that I don't have these kinds of dreams. Is there a way of having one like that again?

3) I have a normal sex life with my wife (once or twice a week), but I have been having a problem lately. I have had about four wet dreams last year. I don't know why but I feel really bad about this. Is there something wrong with me? How can I stop this???


Is neck and back cracking all it's cracked up to be?

1) I read the information on your website about knuckle cracking, and I was wondering if it applies to cracking backs and necks. I know that people often have their backs cracked by friends, etc. because it feels good and seems to relieve tension. Also, when my neck feels tight, I often turn it from side to side until it cracks and feels better. I've heard that chiropractors do some version of this, and call it "realignment." Is this safe? Is there a right or a wrong way to crack a back or neck? Is cracking your back/neck actually therapeutic in some way?

2) As a college student, I sometimes spend long hours reading books or looking at computer screens, and often my neck gets stiff. Like many of my joints that get stiff, sometimes I crack my neck, like I would crack my knees or fingers when they feel stiff. I often wind up doing this several times a day.

My question is, could I do irreparable damage to my spinal system if I continue using this method to soothe a stiff neck? Could I wind up a paraplegic if I continue to crack my neck? Leak spinal fluid, etc.?


Why am I having sex dreams about my dad?

I am having these really weird dreams. They start off with me flirting with an older gentleman and then it evolves quickly into heated sexual passion. The thing that is really disgusting about it is that the older gentlemen switches personalities from random strangers inevitably into my father. I'm really upset about this whole "Electra-complex" thing and it rudes me out. I always wake up when it starts getting too heated and then I feel really ashamed for having dreamt it.

I have a good relationship with my father, although sometimes I wish that he would pay more attention to other aspects of my life other than my schooling and career. Is there something wrong with me? I am happy in my relationship with my boyfriend, I have lots of friends who care about me, I'm doing very well in school, etc., but I don't know why these dreams are happening all of a sudden. PLEASE HELP! Where can I go to seek more answers?

Maybe I should also tell you that my boyfriend and I are very good friends and I love him to death, but sometimes the sexual spark isn't there as it was with prior boyfriends. I don't know if this is because we have been together for so long (about 5 years) or if I've just gotten old and crotchety, but then where do these dreams fit in?


Is anal sex okay if I'm in remission from Crohn’s?

I have had Crohn's disease for 16 years and am in remission right now. Recently my boyfriend and I have been toying with the idea of anal sex, but I'm concerned about it given my health issues. I have a lot of thickening of the terminal ileum walls and worry that the "trauma" of anal sex could set off a flare up and be painful because of the narrowing. Any thoughts? I'm way too embarrassed to discuss this with my male doctor. Thanks!


Why am I getting erections so frequently?

I am a twenty-one-year-old virgin who has just recently started seeing a girl very seriously. I am frustrated at how my body reacts to the slightest physical stimulus. Holding hands, talking about physical affection, even thinking about kissing gives me an erection. I am not thinking about sex, and we are not going to have sex until we are married, but I can't believe how frequent these erections are. I know it's common for guys my age to have erections, but just being with a girl I care about gives me one, and it's not easy to hide, and I don't want her to think the wrong thing. I used to masturbate and view pornography a lot but I finally stopped because I didn't agree with it. I stopped about the same time I met her. Do you think that my past is causing my body to want something I'm not going to give it?


Is it safe to get a UV tattoo?

A friend of a friend told me all about this ultraviolet/blacklight tattoo method. It was deemed unsafe earlier when it first came out, but apparently now it is completely safe. This friend of a friend said she does these tattoos all the time now and is really good about not scarring. So I'm not worried about anything like scarring being seen, I'm just worried about getting cancer and other accusations when ultraviolet tattoo first came out.


Why can't I stay erect?

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!!


Can I donate a kidney to my friend?

I just found out that a friend requires a kidney transplant. I've heard that we are all equipped with two kidneys and can live with just one. How do I find out if I can donate a kidney? What's involved in a kidney donation? Thanks!


Why are my nipples hard?

Is there a reason behind spontaneous nipple hard-ons? Lately one of my nipples just stays that way for the majority of the day. It's irritating! Is there a reason behind it?


Why is my penis so veiny?

I have a question concerning veins on the penis. For a long time now, I have had a vein on my penis which is quite visible. The other day I noticed another vein on my penis that was becoming more noticeable. I know that there are no physical problems with having visible veins on my penis, but I don't like it. What has caused these veins to become more visible and how do I cover them up? I j/o frequently. I know this is a cosmetic problem, but it's an important problem to me. Thanks for your time.


Why is my right testicle riding up?

I have (with much distress) that sometimes when I am having intercourse with my girlfriend, at the point of climax, my right testicle will "ride up" out of the scrotum into my body. I can feel it wedged up there and I usually can push it out back into the scrotum after withdrawal. Is this something I should be worried about?!!! I was born with normally descended testicles, and I haven't been kicked in the groin or anything and it only happens sometimes, not every time. It doesn't hurt when it rides up, but it is uncomfortable and feels strange. It is only the right one, never the left that does this.


Why can't I process spoken speech and how can I find academic support?

I have trouble following spoken speech. It's always made school difficult for me and now it's one of the reasons why I think I'll have to quit college (I'm on leave right now). I would listen to lectures or go to instructors for extra help, but my brain just wouldn't absorb anything it heard. This put a huge burden of self-instruction on me and it made it impossible for me to participate in class discussions.

I think this tendency affects me in other ways too. For example, I don't and never have been able to sit through movies or watch TV — I never know what's going on in them. In daily interactions I manage OK with processing short exchanges of information or instructions, but I don't have "conversations" at all unless it's absolutely necessary, and when I do it's exhausting and unpleasant (I speak VERY little and have never had a friend, so it's no exaggeration to say that I don't have conversations).

Until college, I was always able to compensate for this difficulty by just studying hard and teaching myself. I got high grades and was going to a reputedly good college. Can you suggest any explanation for a problem of this sort and how to deal with it so that I might be able to graduate from college?


Can I get lead poisoning from crystal glass?

1) Many people are buying Swarovski crystal beads to make crafts. I understand that they have 32 percent lead. People are making jewelry and figurines with the crystal beads. Is this a danger to our health?

2) We received a 24 percent leaded crystal decanter from Poland as a gift. We would like to use it for a liquor decanter. Is it safe? Are we in danger of lead poisoning?


Why do I have allergies after moving to a new place?

I relocated to a new area within the past six months. Since then, I have been experiencing congestion in the morning and pressure in my sinus area, such as stuffed nose and difficulty breathing, at night when I lay on my back and in the morning. Although I do not have a cold, I seem to always have a small amount of drainage on a daily basis. Within the past week, I am sneezing quite a bit in the mornings and at night, my eyes are so itchy I can't help but rub them to a nice shade of red. I have never had allergies before, just for your info. Thanks for any tips.


Is it possible to penetrate the cervix?

I've read some other questions on here about men hitting the cervix with their penis and that the penis doesn't go through the cervix. I'm larger than average and my girlfriend is telling me that I'm actually going through the cervix. When we first started having sex it was very painful for her because she thought that I was penetrating the cervix. Now she's past it being painful but still thinks that I'm actually penetrating the cervix. My question is, is that possible?


Should I be worried about COVID-19?

I've been hearing a lot on the news about the new virus [novel coronavirus, COVID-19] and I'm seeing students on campus wearing masks. The news seems to have conflicting information and I'm not sure what to do. Should I be worried? Do I need to wear a mask too? Thank you.


Where online should I go to get trusted health advice?

The Internet has lots of false facts on it. I want to know if I should consider all the health/drug/sex/emotional stuff as fact in science/doctor advice, and what areas are not so qualified in knowing. The reason being is I want to be more informed, and I don't like to be mistaken in passing along knowledge that I don't know to be credible or not.


Should I get a tongue piercing?

1) I'm considering getting my tongue pierced. Is there anything I ought to know before I get it done? What should I look for in a piercing place? Does the piercing ever have negative effects — I don't know, tongue paralysis or something? Thanks!

2) If and when I decide to take my tongue ring out, I worry that there will be scarring tissue or an ugly hole in the middle of my tongue. Is this the case?


Which type of contact lenses are better?

I read that disposable contact lenses are actually worse for your eyes than the normal one-year ones because they allow less oxygen to go to your eyes, and the only advantage is that there are less cleansing problems. Also, it is claimed that inadequate oxygen to your eyes (possibly caused by prolonged wearing of contact lenses) leads to a condition when extra blood vessels sprout around the iris, which leads to sight problems at old age. Is that true?

I am very concerned because I normally wear (one-year) contact lenses from 8am to 8pm, and maybe to 12am during reading periods. I don't feel very comfortable with glasses because they give distorted visions and fatigue. I thought switching to disposable contact lenses would do my eyes good. My current lenses contain 38 percent water. Is this good enough?
