1) I recently had intercourse with a sheep at a friend's house. He is a sheeprancher and one day he was talking about how good it was. He left town for a few days and asked me to feed his animals. I took the chance and gave it a try. The strange thing is that I enjoyed it more than having sex with my girlfriend. When I was a young lad I was molested by a female babysitter. I was wondering if you may think that the earlier incident in my life has affected my sexuality. I liked it so much that I want to do it again, but I am worried that I may contract a STD from the ewe. I have heard that you can.

Could you please help me?

2) I have read about men and women having sex with animals, e.g., dogs (Women on Top by Nancy Friday, Simon & Schuster, 1991). Apart from it being against the law (I think), are there medical reasons why this is not a good idea? For example, are there STDs that can be passed from animals to humans? Are there immunological consequences from depositing sperm into the vagina of another species? Is this kind of sex common?

Is there any data indicating that recurrences of genital herpes occur more often during the winter? That seems to be the case with me.

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.

If my husband takes antivirals or post-exposure prophylaxis can we still have sex with a condom and still complete the process like normal? It is affecting our sex life because he does not want to infect me. I don't want to be infected but I knew what I was getting into from the start. I might start PrEP as it is now available to me. What are your thoughts?

Are there any other sexually transmitted diseases or causes of raised bumps on the vulva?? I have had reciprocal oral sex with two male virgins. The bump is sometimes red and sometimes flesh in color. It causes me no discomfort or pain, and I have no other symptoms that I can recognize.

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?
