I recently began exploring sex clubs/swinger clubs and what better place to further this newly found pursuit than London, described very accurately in a separate thread in this forum as a "candy store" for sexual adventure. Doing my research, I found two clubs that ticked the boxes in what I was looking, specifically good reviews and an upscale/classy vibe.
One of them is the well-known/well-publicized Killing Kittens (http://www.killingkittens.com) who has expanded their lush parties to the States and Canada. My sense from the research is that the London parties are more specific to the 20s/30s age group, so KK has a separate sub-group called Silver Kittens (40+), to which I belong given my 45 years on the rock. Regrettably, I haven't been able to attend one of what seems to be these amazing parties but I hope to very soon and will report back.
However, I did attend a Saturday night soiree with a friend at a London club called Le Boudoir (http://www.leboudoir.club) and I must say it was the best club experience I have had. Le Boudoir is located in East London, with the specific address only given once you have registered, and is about a 15 minute taxi ride from city center. I had a good feeling based on the thorough and efficient registration process (all guests/members must be screened in advance) and was not disappointed by the warm greeting given by the hosts on arrival. The club itself is three levels, with the main level having the dance floor, self-serve bar (BYOB, but all needed glasses, ice, mixers are nicely available) and a number of conversation/lounge areas.
The lower level has theme rooms and play areas with the top floor being a vast playroom. It was amazing playing with my friend and others among the numerous people in that room and it was also quite the thrill seeing the look on couples faces when first entering the room and witnessing all the activities around them!
I must say the whole vibe of the place was excellent, sort of a relaxed sophistication where couples could mingle or keep to themselves. Although we had never been to the club, we found no problem in meeting local couples who all described Le Boudoir as the best club they had visited. Although it has been open only since the beginning of 2015, it looks like it draws quite a crowd as it looked like about 100 people were in attendance on the Saturday night we were there. The demo of the guests were a mix varying from late 20s to 50s, with the most being the 30/40-ish range. The attractiveness vibe was good as well....no supermodels or bodybuilders, but almost all were attractive professionals out for a bit of fun with friends new and not so new.
I highly recommend Le Boudoir and look forward to visiting again on my next visit to London.
