Ladies?

Did you ever wanna please your SO other than oral and vaginal? I don’t wanna sound weird but fuck it! I’m obsessed with my man’s ass lmao. I ate it a few times and I can tell he likes it but really doesn’t want me to do it, because he thinks it’s gay. I’ve heard that brings a man pleasure. If it’s heterosexual sex it’s not considered gay technology right? So my question is.... does you SO let you play with his ass?
