I am really, REALLY glad MC and TGIB are good friends in their own right. It makes so many things so much easier! And I certainly wouldn't mind if they wanted to give a sexual encounter or even romantic relationship a try, but I rather doubt that would happen given MC's straightness and mono-ness. However, if TGIB starts dating a guy at some point I would be very interested in being invited to join in once in a while (assuming I liked the other guy, found him attractive, etc)! I'd like to see TGIB be with a guy, see him enjoying something that I physically can't provide, and see the similarities and differences between him being with a guy (or at least THAT guy) versus being with me.
