problem of women who are willing to be with him if he's cheating but not if he's in an open relationship.
Probably need to move this to a thread but I thought it was interesting because I've had the same experience of meeting women who would be willing to "cheat" with me on my partner but weren't willing if it's an open relationship, that is, if I told my partner. Go figure!?
I made the mistake once of telling someone that my partner didn't know (when in fact she did, she actually suggested it as an experiment to see what would happen). The sex was great but the rest of the fallout was, er, let's say, less than optimal.
