I wish tat my hubby was into sharing, he is good with fucking another woman so I can watch and join, and I am good if he just wanted to screw another woman as long as he told me about it.... but another man would be cheating on him.
My wife and I are the reverse to this. It organically worked out that we're a hotwife couple now. Years ago she cheated on me. That sparked my desires for her to have sex with other men. When she did it again, I confessed all of my feelings. So we decided as a couple that we wanted her to continue having sex with other men. Only she doesn't have these same desires for me with other women. So she can sex with a hundred guys in a hundred days. If I have sex with another woman it's cheating. She would be crushed.
And btw as I type this my wife is in her current boyfriends bed.
