In my case, I had several great BF's, years ago, that introduced me to gentle, fun, painless anal play. Made me a big fan. However, it was after about ten years of marriage (I was about 34), when we just were doing anal much more freely and often, I realized I just enjoyed the tightness, intensity and feel of my man back there, SO much. He enjoys the ALWAYS VERY TIGHT feeling of my rear end as well. For some reason the THOUGHT of anal is simply more of a "turn on" for us both and keeps our love life blazing HOT.
So, if you are like me, and enjoy anal as much as vaginal (or more), WHEN did that shift happen for you?
