Eleonore, and everyone else, you don't need martial arts, or swimming, or cycling, or your porn career, or anything else to justify hair removal. I'm in construction in Florida, where I wear shorts and tank tops about 355 days a year. And I get full body wax. And no one notices, or cares, or at least mentions it. I've had literally 3 people in the last 15 years ask me about my body hair, and a quick answer of "yeah" ended 2 of the conversations. The other one, which was my best friend from HS, gave me a little crap about it until I told him "try it once, you'll never look back." (He shaved for the Big V and has kept it shaved ever since, I say it's the same thing)
