Peeplay does get something of a bad rap due to it being so close to scat and adult baby sorts of things; those are so polarizing that there's not much room to ween anyone onto it and lots of porn that has it will be paired with one, the other, or both.
I think the first thing I ever read with piss in it was Bataille's Story of the Eye. If you're not familiar with it it's this wonderfully odd little short story, quite pornographic, teenagers from well-to-do repressed homes doing increasingly depraved experimentation with each other like farting into the cat's milk dish, stuffing eggs up places, and lots and lots of pee. There's this sort of jovial glee, like it's reveling in just how silly it all is in stark contrast to how dark the narrative gets, that never made me think pissplay was so very dirty (I first read it as a teen myself). It can factor in marking and humiliation, angles which can also be separate from offputting baby roleplay, so there's several ways to go with it without leaning on either of its more offputting cousins.
A lot of the go-to oddballs for the Fenoxo games fall purely into the realm of circus absurdity for me. With sex there's this balancing act where novelty that's designed to approach some fantasies in interesting ways can easily turn the whole thing into a wacky cirque de soliel act and multidicks, two foot dongs, and a cascade of tits flowing all the way down almost always smack right into that territory for me. I'd say I've never found the giant dicks on characters written by Fenoxo himself to be especially erotic, that it's grounding the silliness in a character that's likeable, someone you want to get to know, that keeps them from becoming a circus despite some goofy high concept sex scenes. I'll also say good on Gedan for writing that stall scene on New Texas, that's probably the only time I've found a cartoonishly giant one to be erotic and it's probably the hottest blowjob scene I've ever read.
Generally I think the best way to avoid having a scene that requires some fantasy aspects turn into something that's more funny than erotic is to both ground it with some investment into the character (something that might not work between characters or even people that don't have much between them could work if it's been built up to) and to make whatever the fantastical element is or the basis of the roleplay or even equipment being used follow a basic and easily understood logic. The more obtuse the appeal is the more of a circus act it'll be. With something like male pregnancy and lactation, gender bending and so on you're straying quite far into fantasy territory but the role reversal aspect is a solid basis for it, one that most anyone reading could easily grasp, and one with plenty of room to ground the sillier parts in.
