My wife and I dated for five years before getting married. When we began having sex, I did not have much interest in anal sex. I really did not know much at all about it. I remember shopping for a first porn for us to watch together and specifically looking for one that did not include certain acts, particularly anal.
A year or so before we got married, we lived in cities about two hours apart, so I masturbated more and checked out different porn. I did discover that porn with anal excited me, so I researched it on the web. I asked my then fiance about it, and she was not interested. When we got married I hoped that she would be more interested in experimenting with sex. Over the years she has made some attempts with me, but recently it is something she does not want me to even bring up.
