How men in particular react to hearing of women they know pole dancing is just another factor to consider. As is the willingness of non-stripping women to publicise that they pole dance.
The obvious answer to that is if I gave a shit what some bloke in the office thought about my exercise choices I might as well never work up a sweat.
Yoga? Phworrrr, well bendy in bed.
Tennis? Way-hey, love to see her in a tennis skirt
Kick boxing, judo? Ooh she could dominate me in bed.
Swimming? Nice tight swimsuit yeah love
Blah blah.
I dance for myself, not for any man. Men are not able to view me and the other women dancing. I don't generally seek opinions from those with whom I might randomly interact, colleagues, neighbours, the bus driver, even your Dh and his friends (!) - about how I please my body and soul, nor do I need to evangelise or educate the masses that pole dancing and pole fitness training are now being practised by hundreds of thousands of women for their own gratification not men's.
I should have thought people would, if they paused to even consider it, be able to grasp that pole fitness classes are to stripping what boxercise is to bare knuckle fighting.
And there's always google: try typing 'pole dancing' in and you won't get hits for strip clubs on the front page...
Anyway. That probably sounded defensive. I'm not ashamed about pole dancing, I just think any form of dance or exercise can be perved over, hell, anything women do can be judged or perved over - I know what dancing means to me, what a pole class is really like and I am not concerned by others concern when they don't know, and haven't wanted to find out, because they can't get past the 'came from strip clubs' thing.
Fwiw I loathe boxing as entertainment, people brain-damaging each other for a spectacle but I can see boxing training fitness classes are different and not the problem.
