Butt play and gay..

Guys. Tonight me and my hubby are doing “butt play” as in I’m gonna diner his butt and stuff.. he’s excited for me to suck his dick and finger him at the same time.. all because i read a post on here to him about how a girl does it to her husband and he LOVES it. I’m having some insecurities and I’m afraid he may like it and wonder if he’s gay.. i KNOW. I’m so stupid..
