If it's mainly older men calling you hot what does it mean?😳

It means that guys with lots of history & experience seeing women of all ages, types, sizes have found you to be of a particularly high degree of desirability/allure.

If a sommelier tasted some wine you made and called it amazing...if an experienced art appraiser found a drawing you made stupendous...

if ANY expert found something you did etc., to be of an extremely high caliber...

would you question that?

This is the same, applied to how men look at women.

It might just mean that you *are* as they say, and that *they* don't just look, but they *see* you...for what others simply can't.
