It's pointless having dozens and dozens of characters with an average amount of sex encounters of 2. It's intentionally minimizing the attachment to characters by making it a line up of meaningless one night stands, after you fucked them you couldn't care less if they got shotgunned to the head afterwards since you'll just be doing another quest for another one night stand every single time, never to see them again.
Un-progressable characters, verbose poorly written overly narrated sex scene with cartoony body proportions makes the experience more like a bait and switch, the effort never pays off. The standard is that you get the usual sex reward scene from quest but you don't decide anything about it and it generally doesn't connect or result to anything.
Every npc likes incest, animals, has tits larger than their heads, does anal and acts as if those things are rare. Writing constantly lies telling things that are bog standard in universe are taboo.
