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 care for my girlfriend, whom I have been seeing for a few months now. I have no problem maintaining an erection when she performs oral sex on me. In fact I can climax twice in a relatively short time. We have, however, been unable to actually engage in intercourse, since when we go to put on the condom, I lose my erection. I'm not really having too much of a problem getting erect (i.e., I get an erection, and may lose it early on, but I am able to get and maintain another one for oral sex). What could be the problem? Stress? A lack of physical attraction? I will be grateful for any answer you can provide me.

Quite often when my boyfriend and I have sex, the condom disappears into my vagina. As you can imagine, it is extremely mood killing and a little disconcerting for me to have to reach up there and find it. I read your response to another couple with the same problem, and we'll definitely make sure to hold onto the condom before pulling out. I use Depo-Provera (so the condom is used just to be extra sure), so I'm not particularly worried about pregnancy. What I would like to know, though, is why this happens to us so often? I've never lost condoms with any other partners. I also have the feeling sometimes that it might be coming off before ejaculation. This seems to happen quite frequently (one out of every two or three times we have sex). It's kind of frustrating. Is there anything else we could do differently?

I have given birth to three children. My last child was delivered without an episiotomy. I have noticed a change in the size of my vagina as a result of this. I am too embarrassed to have sex because I feel too loose. Is this common with multiple childbirths? I am too ashamed to ask anyone this. Please let me know if there is something that can be done to repair my womanhood.

The service that you provide is very informative. Thank you for it. When I have sex with my girlfriend and I thrust my penis deep into her body, she says that she can feel it hit something hard inside her body. I can't feel it hit anything. She is very curious to know what it is that I am hitting. Could you shed some light on this issue?

1) What is the average number of sexual partners per year for undergrads?

2) Do you know how many college students are having sex? Are there any statistics? I was wondering if it is lower than a lot of people would have you believe. I feel like I'm the only one sometimes who is not having sex. Thought maybe I'd see if it was true. Thanks.

My new girlfriend and I had sex for the first time this weekend. Later in the evening, she was curious about something... "Where is that thing going???" she asked. She mentioned that full insertion was painful and she wanted to know what I was hitting, and "how far does it go?" Being admittedly a bit rusty on my knowledge of the anatomy of the female body, I told her that I thought it went no further than the "uvula" (whatever that is), but that I would do a little research, maybe see what I could get off the Net and get back to her.

My boyfriend and I have sex almost daily and I usually get on top so my clitoris is stimulated enough for me to climax. But I've noticed that when I come after having sex every single day my orgasm isn't as great as the day before. Can my clitoris desensitize from too much sex?

Thank You!!

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!

1) Is having sex in the shower that is hot or in a hot tub safe? Someone told me the heat kills the sperm. I thought it sounds dumb but I was just wondering.

2) I have a question about sex in swimming pools and hot tubs. Will the chemicals deteriorate a condom? Also, can spermicide be used in water or will it be washed away? Please answer. Thank you.

My uncircumcised boyfriend and I recently started having sex. However, I am his first and he has had tremendous pain while penetrating and even during intercourse. He says the pain is caused from the foreskin being pulled down too far. Because of this, he has never had an orgasm during sex. What can be done to correct this so that we can both start enjoying sex?
