I had anal sex for the first time and after he took it out my butt he put it in my vagina. Now I think I have a bacterial infection?

See answer. It is not advisable to have vaginal sex after anal sex because of increased risk of getting either a vaginal or urinary tract infection or more serious infection. If you absolutely must do this, always use condoms - one for the anal, one for the vaginal, as well as having him wash his penis in between. If you are having symptoms, you should see your gyne or md as soon as possible.

Rectal bleeding. I'm not sure what you mean by "noes potion", but anal sex can cause tearing of the lining of the tissues, making easy entry for bacteria and viruses, especially HIV. Bleeding from the rectum is not normal and needs evaluation. Best to see a health care provider for examination.
