Pornography is an art. Any sort of kinks and fetishes is just another form of art. Often people clam they hate a certain fetish before knowing what exactly they are hating. Or they only like harem stuff because they fantasise to have many girlfriends, without the actual experience that girlfriends can annoy the shit out of you.
Being turned on is a psychological trigger. For example, NTR lovers don't necessarily mean they are beta males. It could be that they get turned on by jealousy. Jealousy is a complex emotion and one might get addicted to the feeling of accelerating pulsation. Similar to people love riding roller coaster.
There is a whole porn World out there to explore. We need to broaden our horizon to truly enjoy porn (and life), and our taste could change over time. For educational purposes, these NTR manga have great authors with state-of-the-art story telling skills and loads of super hot scenes.
