Good friend dated one for quite awhile. They met while boating, IIRC. She was very nice, but very jealous of him. Guess she knew too much about the subject matter to ever be trusting. It eventually ended because of it.
Have been to a few throughout the years, but never really saw the appeal in gentlemen's clubs. Kinda like shooting pheasants at a game farm; free range is so much more fulfilling. When I was single, was my experience that there were just so many places to go out and meet good women who would be offended at being paid.
