How I became a sub..

Married with a decent sex life with the wife,until I had major surgery and she cut off any form of sex.Up until that time I had never thought of having sex with men,tried too take as well as give,but never enjoyed being on the recieving side of of male sex.Meet a guy who I had sex with for ten years who didnt care if he only took my mouth or ass.He used to tie me up a lot..
