I had the same happen to me, my play partner woke me up saying I almost sounded like I was trans. And here I thought she would have been tipped off by the penis. She wasn't very smart...
Nah, I'm kidding, obviously, I'm still not ready to date... Maybe now...
But anyway, I came to add to the choir asking you to be honest, in part for your own safety! Specially since you date men, you know how aggressive they can get when, by their logic, we trick them into becoming gay...
It's been a while since you posted this. Did you tell him? How did it go?
