Rare,,very rare...we are a couple, we both love the LS. The wife from time to time loves to have some chocolate as do I, albeit of the female type. Listen if a gal actually leaves her hubby for BBC then the marriage was not strong from the start. I have no problem letting my wife have fun with whomever she wants, but know she is always going to come home. We have been doing this a long long time, and are far past any of that kind of drama. That type of scenario happens when a couple who is not strong enough gets into it, or both parties aren't totally in agreement and communicate what the perimeters are. This can be alot of fun but you have to have the foundation.
