There are tons of swinging forums out there and notice boards
I have been a swinger for about 5 years and meet lots of couples,single girls etc and have a wicked time.
During this time i have searched the sites and the ones i listed before are the best UK sites by far.
Having to pay to use these sites is a way for other REAL swingers to take you seriously if your just a trial member of any of them i doubt you would get much success since no one will be able to even mail you,send you a pic,number or anything.
In this day and age you gets what you pay for and 99% of free sites or free ads are usually from single sad guys sat at home so most couples wont even look at such an add especially if it looks too good to be true..obviously your a porn model so thats 10 times worse to put a free ad up it will just look fake.
my advice is use
www.sdc.com best swinging site out there...best looking swingers too lol!!
a few words of wisdom thats all
