The parties offer a new group of buddies, long on warmth, short on pre-judgment. A chance to confront sexual/social bugbears: Is it ok to watch/be watched? To masturbate proudly? Am I really desirable? Can I say no and be heard? A chance to watch others do sex differently, maybe get some new ideas. A chance to clarify sexual wants and needs, expectations and fears -- individually and with partners. A chance to celebrate sex in all its diverse incarnations openly, enthusiastically, publicly, collectively. A breadth of permission that unearths sexual personnas people never suspected as their own.
