I ended a relationship about a year ago. I have always seemed to have a yeast infection when I went to doctors before. In my relationship I had went to the doctors before because of discharge and just told them I didn’t need to really be looked at because I know what it is. Well at the end of my relationship I went to the doctor to get a whole check-up. Come to find out that what I thought was a yeast infection turned out to be trichomoniasis. I think I have had it for a couple of years now. I have gone to be treated for it two times. Each time it would go away and then come back. I was wondering if it was because I had it for such a long time?

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!!

My roommate and I were wondering whether or not there was a difference in sleeping with a man with an uncircumcised penis or one that has been cut? My roommate's current boyfriend is uncircumcised and she has heard horror stories about sleeping with men that have uncircumcised penises.

1) Can you get AIDS from a mosquito bite? I heard you can't, but I'm really paranoid about this. Actually, it wasn't a bite — I squashed the bug and all the blood in it splattered everywhere and then here I am with someone's blood on a cut in my finger. HELP! I'm really freaking out. I don't know if I should get tested or not again, because I did get tested before (negative), but the anguish of waiting for results was horrible. Maybe I'm just ultra paranoid?

2) Is it possible to contract AIDS by handling raw bloody meat?

My friend had to have both of his testicles removed because of Testicular Torsion... will he be able to get an erection now?? What are the testicles for, anyway??

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!

Dear Alice, 

I take Valtrex daily to protect me from cold sores I get on my face. I haven’t had one since I started taking it a few years ago. My partner gets cold sores on his mouth and has recently performed oral sex on me while having a cold sore. Will the daily Valtrex protect me from developing genital herpes? How will this affect me in the future?
