Meeting couples
 

I am bi-curious, and was wondering where would I go to hook up with married M/F couples that would be interested in another M?

Check out some "swing clubs" in your area,my state doesnt allow anything like that. :(
Then do a little homework to see if that specific club has any bi/gay crusing activitiy.
If that doesnt work there are a couple online sites that might work for you.....
ALMOST had some luck with AFF And CL.

check out "swinging mags" - i've had success there.

I've got a profile on AFF and have "almost" hooked up but it's mostly guys who respond. Keep in mind that there are 10 times the number of singles guys looking for m/f couples as there are m/f couples looking for single guys there so be prepared to hook up with folks who are below your usual standards.

Craig's List has also been suggested but there doesn't seem to be many people who are looking for MMF 3 ways in my area.

What is AFF?

Adult Friend Finder ,have also recently begun the myspace thing.

tips
 

also, try to think out of the box and keep an open mind on your "ideal" couple. the most fun i've had was my first couple, which started out with just the wife, and then later the couple. and they were over 20 years older than me at the time. very hot experiences.
