That's a definite plan B check. If it's him asking permission for him to look elsewhere then what the ? It might even be both, keeping his options as open as possible. Checking you're still attached PLUS giving himself an excuse to look elsewhere! Yuck. I think I would give a light flirty response, like 'lol, I can't help being a sex goddess' or maybe something a bit more toned down. Don't say anything about his end of it, but don't answer straight either. Well, that's what I might consider doing, not sure if it's correct but no one thing we do here makes that big of a difference does it?
