Nah, it's because it's actually true to mythology. I remember some author (Piers Anthony?) commenting on how many fey creatures seemed to exist solely to have sex with mortals.
...basically turning it into a kind of perverted "I stole your clothes now you have to do what I say while naked" bit... That bit, 3e kept mostly intact. Probably because magical bits of clothing are kind of fey-ish. Binding a faerie to your service by stealing their clothing sounds totally Old World Mythic. But, stealing a girl's clothing so that she'll have to do whatever you say (wink nudge wink) is like...idiot bro logic.
Sadly, that's based on actual mythology.
I agree there's lots of this in Classical mythology, but I don't recall it being true for the Nereids.
Sadly, that's based on actual mythology. Selkies are common myth victims of it as well. And I think djinn fell victim to it on occasion too.
Part of why I really love DnD is that we can have these monsters without the bits of their myth that were really squicky. And I'm hoping they keep that in mind when updating some of these encounters and are willing to drop some of the bits that really should not be kept.
