OOOOH ok.
MOST (i'll give a few actually)
giving: Vittorio (and any iteration of him), DATA 100% DATA, genesis? (although he is aroace, idk bro would eat serious pussy.), ozzath my fucking hated (also prom king too, but... euhhhg)
receiving: maximo (AND ALL HIS PAST LIVES. THESE MFS CANNOT GET ENOUGH.), harley, toby, ... nedwin (well, in a human regard anyways. not normally he thinks that's WEIRD!!!)

LEAST:
giving: mical, emir (his literal only exception is maximo but he always HAS to complain and bitch about it before he inevitably gets wayyyy to into it), glare (his BRACES...),
receiving: mckenzie (LOOK. HE THINKS HAND STUFF IS WAY MORE APPEALING. HE'S NOT GONNA TURN ANYTHING DOWN, BUT LIKE. ITS NOT HIGH ON HIS LIST.), emir a second time (either he's getting railed or touched or nothing is happening sorry. he also will not return the favor sorry.)(HE'S SUCH A PICKY LITTLE BITCH)

SEE THE THING ABOUT THIS QUESTION.... is that most of my ocs do, at least in SOME capacity. Although it's always a toss up on whether or not they'd like to be on the giving or receiving end of it.

FOR EXAMPLE: There's Data, who does have a breeding kink, but he would prefer to be on the receiving end of it. (Side note: he's definitely also into the idea of oviposition.)

UHH then there's someone like Levi, who is way more into the giving end of it (although... well his type in men is men that are bigger and stronger than him, so. he might change up his mind on that in the right occasion.)
OVERALL THOUGH i have too many male ocs who want to get fucked like their partner is trying to get them pregnant.

I guess it depends what you think is weird!

At the heavy side of weird, is Levi, who leans more toward immoral, with his taste for blood and gore, and, as his profile implies if not directly states, necrophilia. However, on the more bizarre side is his fetish for brides, weddings, and anything related… despite not wanting to marry. In all honesty though, he can get himself worked up over most things if he thinks about it right.

UHHH then you have someone like my OC Mattias, who i just posted actually, who has participated in like. petplay, more or less getting cucked (over the internet), and like. watersports. although overall he just goes along with whatever Sylvester wants. hence the getting cucked.

and then there’s floryan, the girl in my pfp, who’s into getting pierced, leeches, and hypnosis. she would probably love a vampire actually.

my point is there are a lot of guys with a lot of different kinks and fetishes, and what is WEIRD is subjective, thank you
