I'd personally just let it stay public and not give a flying fuck about what anyone else says or judges based on my hobbies.
To me, jerking off to whatever fantasies you have in fiction via games, hentai etc. is a completely normal thing to do.
Which is the reason I am open about my tastes on all sites where I've got my profiles public and also because, it's a free exposure which may lead to others discovering something they didn't know about and support the creator because of it so it's a win win for everyone.
