You might find that in your area, most of the swingers are of the "no married singles" variety.
I would try contacting people a little further afield.
Your profile is a little thin on content. It doesn't stand out among the others on offer.
My suggestion would be to read as many other guys profiles as possible, so that you can see which ones really stand out and why.
Also - in the "anything goes" section in the top sticky topics (the red ones) you'll find a "Single men and swinging" discussion - read that too
I hope this is helpful.
