I do not know if this will stray away from the purpose of this site but another option for people would be swingers clubs.
I know of two that will allow single guys to attend. One is in Buffalo and they allow single males in whenever they have a fifth sat in the month. With an exception this month. I believe they will be holding another party next week on sat.
The next club is in Fredonia, nice place and they allow single males in on the third sat of the month but there is a screening/signing up process.
Overall I am impressed with the two. Now I am just trying to find a lady who would like to attend with me so I can go to couples night.
