As a woman, I go thru phases of shaving and not shaving. Although I've got dark hair, my leg hair has always been blonde and thin, so I haven't shaved them in 10 years! Sometimes I'll let my armpits grow out- it makes me feel strong, in a way- but if I start to feel unsexy, I shave them. (it's also a great filter for men- if theyre not into me because of my armpits, I feel like I'm saving time!) Ultimately, I think it's about how it makes you feel- in the same way clothing or jewelry does.
