There's a lot of crossdressing straight men. I don't care what they do but all I ask is that they alert me because this is a dealbreaker. I'm not interested, it's a turn off, it's not sexy... it actually repulses me a little bit to see any "fit" guy in some type of negligee (and I'm imagining someone I'M with, not some stranger).
So they can do whatever. I just hope they're honest with their partners.
