I have also been turned on by guys I later find are transmen. Hotness is undeniable. Personality and attitude are also pivotal. I am thinking of one young man in particular I know who is so smart, charming, beautiful, and sexy that I could never turn him down.
Because of my own sexual history, I might even find such a man to be sexually compatible. Only time would tell whether it could turn into an enduring relationship. It might also have to be an open relationship so I could get dick too.
All that said, I am proud to be able to open my mind to it.
