My boyfriend (20) and I (19) have been together for three years. We really do love each other and so we decided to have sex about two years into our relationship. First things were great, but a few months after we had been having sex regularly he changed his mind. He said he liked me better when I was innocent and that he hated what we did. He stopped all those cute romantic things like telling me I was pretty and writing me love notes. No matter how hard I try, I can't get him interested in me again. He used to tell me he was going to marry me and we always talked about the future and everything but now he just says he doesn't know what the future will be. Obviously, had I thought this would happen we wouldn't have had sex in the first place but since I'm stupid... we did. What do I do? To call it quits after three years is just too much for me to handle... but I can't live like this anymore. HELP!

I have doubts: I am a 14 year old guy, I'm from Argentina now living in Florida and I have always pictured myself with girls in romantic relationships, and I still do. But now I enjoy watching gay pornography. When I picture a two-man relationship it disgusts me, but yet I prefer gay porn. About girls, I only feel sexually attracted to some but I do only picture myself with a girlfriend in a serious relationship. Whats going on!? I need help!

I'm unclear on how condoms are supposed to be effective in preventing female-to-male contamination during "plain" sex, I mean insertion of the penis into the vagina. Let me explain.

Latex is an effective barrier to virii and germs. I get that. As far as protecting the woman is concerned, I've no trouble believing it works. The STD virii or germs are present in the semen and/or pre-cum; these are "emprisoned" by the condom, don't get out, and don't get into contact with any part of the anatomy of the woman. She's protected. The sweat of the man does not contain these virii or germs and thus no risk with the rest of the skin-to-skin contact. But in the other direction, I don't quite get it.

Me and my boyfriend have been dating for about a year now. I am 16 and he is 18. We live in Egypt. In the first 2 months I used to ask him embarrassing questions about sex - I thought it would break the ice between us. He used to say that he does not want things to go too far, at least not for now. I kept asking those those questions, feeling pushy, but he started asking me if it was okay if he touches me and so on...I said that it was okay. From the 4th month and till now we have been having regular anal sex - as he wants me to stay a virgin - yesterday he said that he does not want to do any more sexual activities with me. He said that he still loves me and that we are still together and that he does not want any other girl but he said that I was too easy - I know that I was easy but it was only because I truly love him - Did I do anything wrong?!?
