If you are interested in characters tease and torture each other in a sadomasochistic way this could be your picks.
Based on the main characters, Tarou (MM!) loves to be the masochist, similar to Sayo. While Utena (Mahoako) loves to do the sadistic teasing, similar to Mio. Together these anime is just a cacophony of swearing (lots of it), sex jokes, misunderstandings, and just Ecchi in general.
If you're lucky, you may even find something that appeals to you... you weirdo...
