All depends how strong your relationship is and whether it would recover afterwards. It's still infidelity whether it's gay, straight or with pans.
To be honest I've never really particularly liked being in monogamous relationships, so if my partner came home and wanted to get with anybody at all I'd be pretty ecstatic. This is, unfortunately, vanishingly unlikely!
No, and I reckon at least 80% of people saying yes would end up regretting it. Tbh I'd need to have a long old think about the relationship in general given that she's essentially wanting permission to cheat.
Narthen Terence It's a yes from me. Life is simply too short to get in the way of any ***** on ***** action.
