I think it's more about the porn than necessarily about the sexuality. We know that things like porn provide a neurotransmitter reward to the brain, but with repeated use of the same kind, the reward dwindles. The brain wants novelty. So these guys start to look at trans porn. And maybe these guys haven't tried man-on-man sex at all. It's just a fantasy to them. Or maybe this is a gradual way for men to discover their bisexuality.

Think of what Marsha P. Johnson said -- that he dressed in drag as a prostitute because it attracted more clients.

But AskGayBros is the wrong place to ask about stuff like that. There are a lot of guys on there for whom sexuality is purely binary. They have no patience with someone who's in a process of discovery. You're either gay or straight or maybe bi, but there's a contingent there that barely believes in bisexuality.

We also know that for many AGP transwomen, sissy porn has been a kind of gateway drug into their "becoming a woman."
