Baby girl, I would not advise bringing up his best friend. Most who are into sharing do it with people they don't know. If he was open to his friends joining he would bring that up. Lol it great to double team a lady you met at the bar with your buddy but someone your in a relationship with....
Mentioning him would raise a lot of flags to him and chances are he would never trust you around his friends again. Go the stranger route to start with and progress from there. The less attraction you have to the guy the easier it is for him to become accepting of it.
