Straight, Yet Bi?

Lately, I find that I am having these recurring fantasies about performing oral sex on a well-endowed male. I have even fantasized about being in the center of a group of well-hung males. When I was younger, I did this with one of my cousin's friends. I think I'm having some kind of flashback, or maybe deep down it turned me on. I just don't know.
