Men are dishonest about their sexuality. I've have been accepting of my being bi since high school. There were a lot of "straight" guys who were't above letting me suck them off on the regular back then. At the time I was "straight" too however somehow I ended up with a lot of dicks in my mouth. Strangely enough, as I got older I found myself with a few of my friends dad's dicks in my mouth too. Then "straight" guts from work and "straight" guys from college and so on. I'm a single. I like casual sex. Most of the casual sex I have is with "straight" guys both married and single. Why the dishonestly? Why not embrace your sexuality and be honest with everyone? You, and they, will be happier for it.
