Bf and bestfriend...

Today I was sitting in my kitchen w/ my best friend and boyfriend. After having a normal convo she asked who had better massage hands and volunteered my bf to give her a massage. Am I wrong for being a little upset at both of them? Her for suggesting it and him for acting on it. It’s weird asf to me. I even said “I don’t wanna see this” and walked away and they were like wtf and continued.
