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?

Hi, I was recently treated for some sort of bacterial infection in the vagina with metronidazole pills that I took twice a day for a week. Toward the last couple of days of treatment, my discharge came out in long, oozing strings pretty much every time I sat down to go to the bathroom. It was pretty gross! I figured it had something to do with everything being cleared out, but it still lasted for a day or two after I stopped treatment. Now, I've been off of the antibiotics for nearly a week, and I'm still noticing a little bit more discharge than I would probably want. Is there kind of an adjustment period here? Did the medication not fully treat the problem...or did it cause ANOTHER one?
