Only a very, very small percentage of paedophiles are exclusive paedophiles. This is more like a bi person becoming more gay (or straight) by exposing themselves to more gay (or straight) porn. People can focus in on particular aspects of their sexuality or ignore others, and that’s before fetishisation comes into play where the mind projects sexual meaning onto stuff that’s not primitively (as in instinctively) sexual.
Yes. Even if you’re a 110% straight dude, if you set your mind to it, with enough practice, you can learn to enjoy sucking dick, or at least having your dick sucked by a cute femboy. At the same time mere exposure to gay porn doesn’t do the same and that’s not a contradiction as your usual 110% straight dude has no interest whatsoever to setting their mind to learn how to enjoy sucking dick, there’s neither inclination nor reason to, the porn is just going to go straight past them. 90% straight? Much more likely. Neither is going to lose their original attraction to women, though, the most you get is nothing happening on that front because they’re occupied elsewhere. And that’s exactly where we want the sexuality of paedophiles to be: Occupied elsewhere.
EDIT: I’ll assume the downvotes come from people not realizing just how plastic our mind is and not random reactionaries. Not on my lemmy.
