I don't find hair in a woman's armpit attractive or sexy at all.
Legs - I rather have some stubble then hairy legs.
Far as downstairs - If it's natual it needs to be 'groomed' and not going wild. Same with guys. I'll never why they have every pube they grew since they where a teenage. Everyone needs to keep
it trimmed.  It stinks - you sweat so does your junk and the hair keeps that stink there.

Yes for as hobbying you come clean but outside the hobby sometimes the moment just happens and not really going to say "oh wait-let me clean up I just mowerd the lawn, so I don't smell like a gym sock when you give me a knob job.'

All a matter of personal preference.

I really don't think that a woman that shaves it all looks like a 10yr old. Not anything that ever crossed my mind. Then again his is all subjective.
