Anal Sex Questions ..

I recently tried anal sex for the first time and he like it (Shocker), but I don't understand how that is pleasurable for women. After the painful part was over it was nothing. I mean other then the fact it just feels strange there was nothing about it at all that was really even worth my time, at least for me. I didn't feel anything. I don't know it was my first time and I don't know what I'm suppose to do really. Maybe some of you ladies could help out. Is there anything I could try to make it more pleasurable for me, or honestly ladies is this kind of thing just for the guys pleasure?
