i can think of at least 2 other stories with this plot but i think this is the one you’re looking for

Cold-Blooded Beast, Hebi no Yomeiri, Summoning a BL Fan to Another World, Samezoku e no sasagemono these are the ones that popped up first in my reading list. I didn't check if all of it has two genitals, so you can read to check it out. Not toxic relationships btw, mostly green flag tops if you like those. ╮( ̄▽ ̄)╭
Is there any bl top characters with two genitals?
