Cyber brooooooooo idk if I asked this already but have you read the manga Nana To Kaoru??? If not you should! It’s not rapey like other mangas and it has piss kink and bdsm (no actual sex though) and its super cute and v informative about bdsm and different kinks. I myself am not into bdsm but I like to reread it every few months. you should def check it out.
