I have started "cock-stuffing" in the past year or so. I use a glass thermometer and insert it into my urethra. I know that this is wildly dangerous — as the glass could break — but I thought it safer as it is manufactured very smoothly.

I know other men who use a variety of implements — pens, markers, tubes, etc., but I have only done it a few times — and it seems that the glass — while not safe as it could break — is safer as it must surely be smoother.

I use my own saliva as a lube — as I am not sure if a personal lubricant — i.e., Wet, KY jelly, or the like, is safe. Not that putting a piece of glass into your urethra is all that safe to start with.

My question — in the end — is personal lube okay to use? Is this a common fetish — I don't do it often — and it doesn't seem to affect me adversely afterwards.

Thank you for any light you can shed on this.

I have been seeing my boyfriend for four weeks. He has told me all about his past relationships. Is it safe to stop using condoms now?

1) I was wondering what information you have on the male birth control pill and when it could possibly be released on the market.

2) I am a man and I want to take a safe, effective, and reversable male contraceptive. Is such male contraception available?

After you have sex, how long should you wait till you do it again?

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?

The emergency contraceptive pill: Does the amount of times I have unprotected sex in one night alter the effectiveness of the emergency contraceptive pill? Will the pill work the same no matter how many times I have unprotected sex on one occasion?

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?

Is there any way for a woman to combine her birth control pills to get the same effect as PCC (post-coital contraception)? If so, what is the dosage? For example, could I take three or four or even all of my birth control pills at once in order to get the same effect? I need to know the answer: How many pills will equal one PCC dosage? Please tell me because otherwise I'm going to take the whole month's worth at once.

I've heard that you could order oral contraceptives over the Internet without having a prescription or an examination. Is this true and if it is, where do I order them?

Could the birth control pill be causing my weird food cravings?
