Although I have had many more relations with women than I have had with men (3) I have always known I was bisexual. I love the company and companionship with women, and I love the feel, scent, and touch of a women, but I was always kind of turned on when I would go to an adult theater, and see men jacking off, or sucking another guys cock, while watching the porn movies.
It wasn't long before I started getting in on the action, and have been masturbating, giving and receiving oral sex, with both men and women ever since.
