thinking about an attractive guy being forced into crossdressing, but less about the clothing and more about his mental state. how embarrassed he feels about his cock stiffening just from wearing a skirt, or the sensation of stockings on his legs. how much he doesn't want to be turned on by it, but is. how he's internalized the idea of clothing being degrading and it being "gay" in his mind, so he's having unwanted thoughts about sucking cock and being topped. his arousal directly being linked to feeling degraded. things like that.
i can't get into any of the actual crossdressing stuff i've seen online, it's all just off-putting sissy and "femboy" stuff that either glosses over the mental aspect, lacks it entirely or reduces it to a simplified, generic brainwashing fantasy. the other thing is that he still has to look like an attractive guy when dressed up. no fake tits, wigs or heavy makeup. long hair is nice, but it can't look or feel too manipulated.
if i had to have one of those fetish split screens, it'd be one with a scene of the guy living a normal life, doing normal things, next to a scene of him stroking his cock while crossdressing and trying to strike a balance between moaning enough to feel "defeated" and being quiet enough to not be heard. he'd have to look hot in both.
