Are men or women more sensitive about nudity?

Sensitive ? I myself will be nude whenever I can,and prefer it at home during warm months! A female friend says her husband as well as the husband of her friend also go nude. She thinks it a guy thing,and has no desire to show off her body. Note; we are all in our late 50's and she doesn't like her body I guess.Others nudity doesn't bother me at all.
