Bachelor Party

Hey Guys, 
My boyfriend is going to a bachelor party next Saturday and I'm feeling really insecure about it. He is the best man and the group chat was organising strippers and all. They were saying the best man and the groom get a stripper. I feel really uncomfortable with this. I am insecure, i know my boyfriend loves me, but the thought of another women dancing sexually in front of him makes me quite upset. I don't want to say anything because I want him to have a good time. I just don't know how I'm going to feel comfortable with myself and body after I know he just got a strip tease from someone skinner and prettier than me. And she has all the right moves. I don't want him to not go. I want him to have a good time. But for me, how can I overcome this fear and insecurity? What can I do to help myself feel ok and better about this?
