How it began?

Hey all, especially the women, I'm curious as to how you discovered you liked anal play? what was the first occurrence?

Some guy I dated in collage suggested it to me. We both were into enemas and he said that anal would a natural thing to the next step. So I tried it on all fours on my bed while he slid it up my bum. It did hurt some but it turned me on more so. It became part of our sex games.
