Can I stick a hot dog in me?

My boyfriend and I were having sex the other night. He wanted to try anal sex. I've never had anal sex and I wasn't sure about it, but he put his penis into my anus and he only got it a little bit, but couldn't go more than halfway. After a while I told him we would need lubrication. But we didn't have any. Then he stuck his penis back into my vagina. I told him he should have washed off first. It's been four days and I have smelly discharge and it burns a lot. I suppose I have an infection or something from what he did?

I got something called bacteria vaginosis and while some doctors say it's not a STD, a lot of the state health department's professionals consider it one. They say that although girls and women get it sometimes without sexual contact, a lot of them get it right after having sex. I have, and will consider it one. I've been treated for this thing three times and it never seems to go away. Do you or could you consider BV a STD? I didn't bleed after the first time, just horrible pain during and up to one hour after in my vagina. But the next day I felt this horrible cramp-like pain in the pit of my stomach like if I had my period -- is that normal? Will this thing ever go away?

I've read your article on vaginal secretion several times but I'm still confused. All of my symptoms of my discharge point to normal except the smell. I have to constantly spray perfume(not down there) on myself because I'm afraid that everyone around me has to deal with this very strong smell, almost like urine. I'm not sure what to do. I try to keep clean in the shower and I'm a virgin so I don't think I have an STD but it's getting to the point where it is really becoming a pain and I'm so self-concious whenever I'm around people. Occasionally it will also feel like my vagina is just dripping wet. I look and there is some discharge but not enough to warrant feeling like I just had an accident. I can be walking around and then all of a sudden it just hits me. It's terrible.

Do I have some sort of infection that I need a prescription for or do I just have really bad vaginal secretions?
