Since iv been married my husband and I have talked about a 3 sum (mmf). But it's always during sex or just after. I think he would go through with it but not if it was planned. I think I'm the same. If we were out and a bit drunk and a guy came on to me when he was at the mens room I think things would develop from there. I think I would prefer it to happen like that. Or at a party with one of his friends there and we shared a cab back to our place, something like that. Has anyone got any experiences on this very hot subject. X
