I'm kind of in MsJoann's situation. Lot of daydreaming of intimacy though I rarely find myself attracted to any male in particular.
But boy-crushes... Wow. I had this hottie roommate who was gay. I was not interested when we met, but we knew about each other. He was very athletic and wore those short summer outfits now and then that eventually sent me into guilty little fantasies. I did wind up giving him a back massage at his request but it didn't lead anywhere. I was even cooking for him at one point. I came very close to surprising him with a maid's outfit but never ordered it (too many roommates and visitors).
Another time I was in the library when a guy...um...sort of pinched me on the tush. I didn't know how to react and just froze. That night I dreamed I became a woman as went on a lunch date with a man.
So yeah. I guess being with a guy wouldn't be so bad. The way I feel about it is the same way I felt about wearing a bra before I started dressing. Very curious, but unsure and a little embarrased.
