How can I avoid jealousy of a bachelor party?

I've never been married, so this is strictly opinionated. Hopefully, there aren't any trust issues in this relationship. Assuming there aren't any trust issues, talk to the fiance' about boundaries. What is allowed or not allowed at the party? What kind of touching, if any? Suggest the party to be videotaped and watch each other's party. Communication is the key, especially if you feel you may be jealous. Be specific. We won't do this or it's okay to do that. Don't hold back!
