I am a male (straight) and I have a female friend (lesbian). Years ago we used to go trolling (occasionally) for nooky together. Sometimes we would have a threesome with a willing wench which was very interesting to say the least. At times we would compare notes on the "hotties" we went out with. The most fun we ever had was with the AC/DC wife of a large southern city mayor. Imagine the possibilities. Anybody else ever try this?
