Me & my girl had anal intercourse. I was wondering if we could have caught trichomoniasis from it?

we have been to getter fro two years and i honestly have not been with any one else. when we first got together we where treated for chalymydia which can from me. is it poosible for us to spread this to one another through anal sex if so, where did it come from?

i had trich and it can be from being dirty or not cleaning yourself tell her and you to go to the doc because for her it could lead to p.i.d and its not hell hell but i went through all of that .. thats why im celibate now but yeah go to the doc plz

Probably not. Trichomonias can be passed from woman to man, or woman to woman. Men can not pass it to other men. But men can get it from one woman and pass it to another woman, without him knowing.
Men with this usually do not have any symptoms. If any, it is only mild burning when urinating or after ejaculation.
The woman with this will have obvious symptoms, foul smelling discharge from the vagina, sometimes it is a frothy green discharge.
The point being I guess is to make sure you both are treated even if you do not have symptoms. If only your girlfriend gets treatment, you will only pass it back to her.
To make you feel better, this is the most common STD. Millions of people have had it, and millions more will get it.
Hope this helps.
