My circumstances aren't quite the same. For the longest time I've tried to get my reluctant wife in the position of being "hit on" by a persistant and persuasive guy in public. Somebody who "has game". She usually goes to a local Indian casino about once a month and spends a couple hours there playing slots.
Without going into too much detail, I've been in contact with 5 different guys, not just from this site, that have said they'd be very interested in trying to "get in on the ground floor" so to speak, but when it came time to pull the trigger, they all ghosted me.
I know that there's no promise of sex for them in my case, so take that into consideration. All that aside, I'll still keep trying to make it happen, although the results are discouraging.
