I (21M) have never dated women, yet I wanted to vary my dating pool (for several reasons).
I have always been very passive in dating, as satisfying men tends to be extremely simple most of the time, and I also struggle with some mild body image issues, which only tended to exacerbate some of these passive tendencies.
Not only that, I am relatively tall (182cm or 5'11, I think, I don't use imperial), which tends to make me loom over most people (esp. women) I know, with them ranging between 150~165cm (4'11~5'4), which also makes me somewhat self conscious of being menacing or intimidating.
