If the two of you have fantasized about it he wants it. Guys are really conflicted about this. We want it but we are terrified to bring it up to you. We don't want you to feel we are weak, but you have no idea what goes on in our minds (or maybe you do). And we want you to still love us after you have taken a lover. We may (probably) even want to have him a bit for ourselves. Sometimes the lady has to man up and take a bit of charge. He will love you for it. And you deserve it. Choose wisely and take a lover. Or many. I'm certainly available.
