Yeah but that is just a physical thing because they’re Succubi/Incubi. It’s a “cultural” norm for the race, I personally don’t like stories with large harems once you hit double digits it’s kinda excessive. Plus I feel like you should have an emotional connection with someone if you’re gonna take them into your harem. I guess you could reason that an immortal could have quite a number of women and still have an emotional connection but this is just a young guy so it’s meh.
Edit: The only story I’ve read where the MC seems to treat his women well (not ignoring them after adding them to the harem) is Dual Cultivation by MyLittleBrother and the MC still has plenty of meaningless s*x, of course he is an Immortal who specializes in Dual Cultivation but it’s a unique view on the concept where he doesn’t just use women for his own needs.
