Most girls will tell you no.
Anal sex is something that takes a lot of practice, communication, time, lube, and some pain. Until you get used to it - it can be very uncomfortable and even painful.
Me and my fiance to have anal sex, but it took a long time before we could do it and it didn't hurt.
I personally don't enjoy it but I know some girls who do and there isn't anything wrong with it, it's just not for me and makes me feel uncomfortable.
