Nightly Bi Fantasies

I think about sucking cock every night. But I love women. I love my wife and I want to fuck her all the time. I’ve told her that I think I’m bi. She thought I was just obsessed with my own cock. But I wish she would watch me suck another man. And that we would both fuck her, separately and together. And that I would be inside her, and he inside me.

I masturbate to such thoughts. Then I cum. And wonder am I really bisexual? Or does the thought just get me hot? And is there a difference?
