Guys: Question. Would you care if..?

Not at all - I'd be extremely happy! :) All larger natural sag a bit (if not right now, then soon!) - it's their natural shape and absolutely honestly, it's all part of their charm! Absolutely no exaggeration - it's exactly as they should be, and very attractive. Don't worry about it for a moment, be proud, and on behalf of your boyfriend let me say lose that bra, it's not helping! ;)
