Why are single woman impossible to find!!!

We have been searching, (sometimes I think it would of been better looking for the holy grial), for a nice, sexually orientated woman to join us for either a one off or ongoing sexual friendship now for ohh about 10 years. She has been longing to explore the intimacies of another woman without loads of other people watching, i.e a swingers club, or another male trying to jump her the moment he gets a chance, ie other couples. Dont get me wrong we have done the couples thing, but we knew the ground rules in that situation and we were happy for all to be involved. What we are looking for in this case is different. Its not so much about full on sex as about exploration, intimacy and 2 woman getting to know each other on a different level. Anyway enough rambling, does anyone have a tip on how to solve this dellemar, or are we not alone here. DAK
