Some random cc porn habit headcanons because why the fuck not
Scar - used to watch exclusively straight porn and laser focus on the woman and not look at the man at all. now he dabbles in the gay stuff but he only looks at the top because... that's less gay? he watches way too much stepbro / age gap / stuckporn stuff. and has niche kinks but refuses to explore them. never looks at porn with disabled actors. barely has the time or privacy to actually jerk off and the cleanup is a mess so it often ends up being an edging session. developed an edging kink (and breathplay kink) as a result. sometimes indulges in unsanitary stuff like piss or whatever because his hypochondria translates into nasty kinks even if it makes him feel icky. all his porn is visual or at least audio. audio alone doesn't always do it for him and he doesn't get on with reading due to the dyslexia.
Grian - you could not pay him to watch gay porn. but you can find him listening to sexy boyfriend asmr. because that's not gay. obviously. he saw some Pokémon porn once and won't admit that he liked it. mostly watches very boring very normal missionary heterosexual porn, but honestly he finds it hard to get into. he would definitely prefer amateur stuff, something gayer, or something a bit more kinky, but he won't let himself indulge in more than, like, maybe a breeding kink video. also he hates cheating plotlines.
Mumbo - gets horny watching obscure european arthouse gay yearning movies with maybe a sensual touching scene in them and then after he's rated it in his film journal he gets Vicky to peg him. while he rambles about the film to her. otherwise does not watch porn.
Cleo - doesn't watch porn, sometimes reads amateur erotica or fanfiction. jerks off bored style often without any other stimulus. they know they're hot as fuck though. sends pics of their bush to [REDACTED] just to make them squirm.
Etho - you don't even wanna know the kind of pervert shit he's looking at on the internet. (it's [EVEN MORE REDACTED] and tentacle porn). also indulges in femdom, forcefem, and pegging content, but feels guilty about it after. jerks off multiple times a day and feels guilty about that too. but also turned on by what an awful pervert he is.
Joe - he's exclusively reading novel length erotica and forgetting to jerk off because he's too invested in the plot. he does have crazy e-sex to make up for it though. he's a busy guy and rarely actually has time for all this stuff, but he doesn't really have a sexuality preference for the stuff he reads despite being straight. as long as it's dramatic, fantastical, and well-written he doesn't care.
Gem - she reads fanfiction about her coworkers fucking each other.
Pearl - I don't think it has occurred to her that she is allowed to watch porn. alternatively none of it gets her off. I just genuinely cannot imagine her even attempting to watch porn. I'm so serious. she gets enough attention from her boyfriend I guess. she's also gay for gem but she doesn't know this.
Ren - like a way more repressed and weird version of whatever Etho has going on. he watches gay porn but he's not normal about it. has some insanely online kinks. use your imagination (he does too). fantasises about his male coworkers wanting him so bad they leave their wives and fuck him nasty. he's very alone so he jerks off a lot.
Xisuma - normal vanilla heterosexual porn but also sometimes he looks at really well maintained computer hardware and jerks off . he thinks he is the devil for this.
K that's all I have for now.
