Only one of my friends has ever bragged about having a threesome. He's bisexual, but he had a threesome with two women.
Years ago, I read an interesting book about Miami, Florida. I think it was written in the late '80s or maybe early '90s. Anyway, the author commented at one point that some of the hotels that he stayed at in Miami tended to put three mints on the pillows of each bed, apparently because threesomes were common enough at that time, at least in Miami.
Good decisions come from experience. Experience comes from bad decisions.
