Well, I dunno about Houston as I've never been to Texas. (I was watching this show on ABC last night about teenage parents and they showed a sex ed class in Boston vs. one in Texas. Scary how they go about it in Texas - making kids sign these stupid abstinance cards, putting the fear of sex into their heads, etc. I wish I was back in High School in Texas and I'd laugh in their faces. Anyway, I digress....)
I've only been to two swingers clubs and both are in Toronto. Both feature on site sex where essentially there is the "front room" and the "back room". The front room is a bar like any other (except there is nudity from time to time) and the back room is an all out sex party.
Anway, there is
Club M4 - Toronto's Hottest Swingers Club
and Club Wicked
http://www.wickedclub.com/new/home.htm
Long story short, Wicked is a younger crowd (more eye candy) while M4 is an older crowd (mid 30's and up). M4 is more sexual. Both feature lots of swapping going on.
Since I go with my GF, it's not a problem getting in.
Wicked allows select single guys on Friday nights, but only couples on Saturdays. I've only ever been on a Saturday. My GF isn't really interested in a gang bang situation, but I'm all for it if a woman is so inclined. One couple we met - D and L are active swingers and they regularly go to Wicked on Friday nights so she can gang bang. (I find that interesting because I don't find her that responsive in bed, though that could be a case of chemistry between her and I.)
M4 just had their first single guys allowed Friday last week. Saturdays are still all couples. I have no idea whether they are going to repeat the experiment or not. (It's a regular thing at wicked.) Though M4 has Bi Sunday nights regularly which single guys can get in. (Presumably to hook up with couples - dunno, never been.)
So, to the original poster......
Book a flight to Toronto - though there's a garbage strike on right now - so my beautiful northern giant is getting kind of messy
Since sex clubs are legal in Canada, it's not too hard to spot them - just look them up in the phone book! (or on line). The state has no business in the bedrooms of the nation.
