That's an interesting theory. There was a lot of rumblings about whether he hooked up with ladyboys in Thailand or not, while that's just speculation, it is a way for gay men to have sex and relationships while trying to pass as straight, and very common in homophobic cultures like Thailand and like Lloyd's upbringing.
I think it's more likely that he's straight, but into some very weird gross fetish stuff, or underage girls if the claims about him are true. He's talked about his porn addiction a lot, going back decades, and it's well known that that can desensitise viewers, so they escalate and look for worse and more extreme things to get off on.
That's the main reason johns cite too when interviewed: most of them are in relationships or can get consensual free sex, but they say they use prostituted women because while their wives and girlfriends will have sex with them, they refuse to do the nastier things they want to do, so they outsource it to someone who can't say no or can't afford to say no.
Tbh once porn addicts get into fetishes they often don't much care about the sex of their partner, as long as they're indulging whatever the fetish is. It's sometimes called pseudobisexual, because they're not really attracted to men and women but to the fetish instead. Could be any of those.
Either way, he needn't be ashamed of his feelings for adults, but he absolutely should be ashamed of punting and cheating.
