Have you ever touched your so's butt?

My boyfriend & I experienced something new last night. I started playing with his butt& he loves it. I wouldn't have liked this at all butt he got me into it with playing with mine. Since he is a man do you think he feels weird about it deep inside? Or have mixed feelings? He went to work without giving me a kiss& telling me he loved me. Most likely from keeping him up all night😇 Womdering how he feels about it. Has anyone else been in the same boat?
