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) Recently, during intercourse, my condom broke. Now, of course, I am very worried about it happening again. I am constantly checking the condom during sex and find that the condom is extremely tight against the tip of my penis whenever I check. I am afraid it will get tight again and break. I'm not sure what to do or where to go. Is the condom supposed to be very tight at the tip or not? Any help would be great.

2) Here's my query. I recently started having sex, and we are committed to using condoms. What is the "right" way to use a condom? I know how to put them on and take them off. But I'm petrified about having it break or come off. Also, someone told me that I should pull out immediately after I ejaculate. Is this true? This has happened before, but I have "stayed in" because I wanted my partner to have an orgasm. Is it really important to withdraw immediately after ejaculation?

I was wondering what exactly a cock ring does? And has it been known to be effective at what it's supposed to do? I have seen them in several places and have been too shy to ask exactly what their purpose is.

What are the risks of HIV infection for the passive partner of oral sex?

I'm 18 years old and have never had sex. But three years ago, I started masturbating. And this past week I have been having swelling in my vagina. You can't get any STD on your own, can you? I'm scared to go to the doctor because I don't want my Mom to know I have been doing this. Please respond.

1) I have recently discovered that I have what appear to be crabs in my pubic hair. They are itchy and annoying and appear to be laying eggs. How do I get rid of them?

2) I think I have pubic lice, a.k.a. "crabs." Do I need to see a doctor about this problem, or is there over-the-counter medication of some kind I can use to expel the little buggers from their new home? Also, I'm curious as to how I got them since I haven't had sex for several months and this is a recent development. Can one contract this problem from sharing clothing, towels, or bedclothes?

1) My partner seemed to pass urine while ejaculating. Is this normal and what would be the cause of it?\

2) Every time I feel like I want to orgasm, I stop because it feels like I have to pee. I don't know if I have to pee or if I'm really having an orgasm. Please help.

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?
