Whats a good way for my wife and i to pick up women to fool around with?

My wife of 12 years has had sexual experiences in the past and misses a womans touch. We want to pick a good looking woman to be our toy but don't want to go to swingers clubs because the men are too aggressive there. Should we go to a lesbian bar? Will I be welcome there? Topless bars? Advice. My part in this is not to penetrate the other woman, my choice and prefference. I've had plenty of women so I'm don't have to have it. Advice please.
