No. I would be uncomfortable with it. I'd rather they kept it to themselves, but also find it odd that their partners/husbands tell them!
A friend of mine once told us she wanted
us to think her boyfriends were hot but, apart from feeling weird about that, it was totally impossible because we all have such different taste in men! None of her boyfriends were ever 'hot' to any of us. Her fiance is lovely and they really suit each other but I don't think he's hot at all.
I would be very surprised if any of my friend's spouses found me hot at the moment though, and it doesn't bother me. I only wish to remain 'hot' in DPs eyes
