i did not liked it either from the beginning until i met someone who i really liked. he is a top and insisted fuck me. it was not enjoyable at first but after a month or two i got used to it and start to like it. Now i only have anal sex. he almost always fucked me till i shoot and I don't even need to touch myself. And a lot of time when he sees me cum and would just cum in me at the same time. I guess you just need to meet someone who you really like and keep on trying.
