Maybe it's because you're 20 or younger. Perversion increases with age. I assure you your preferences won't be the same in 5, 10, or 15 years. If you don't like it, find something you do. I hated NTR before; now I'm bored with pure love.
Actually, I have nothing against NTR. I just don't understand how you can make art only with BBC and nothing else but BBC. Well, almost. Don't you get tired of the same theme yourself? Not to mention that often it doesn't even make any sense. I would be happy to find something I like, in other words something that is more diverse, but the problem is that the vast majority of AI art is BBC themed only for some reason. At first, I even thought it was some kind of preset in the AI settings, because otherwise it's hard to explain such a prevalence.
