Great thread!
Not a swinger, but I had a few adventures.
Been with the same girl now over 5+ years. She's adventurous but no other couples yet. It has been talked about and is not off the table. Preference of course is just another girl brought into the mix and that is also an option but I can't really seem to eager or start making suggestions. Gotta let her make that move, but I'll be there to play along.
