What It's All About
It's perfectly understandable, and frankly not all that damaging. Not like, say, being a closeted homosexual working for people who want gays removed fromt he face of the Earth. Kink is only slightly hidden from view, and can be as safe or as dangerous as you care to make it (hello, motorcycling!). I don't have any real need to hide my own proclivities, what with no kids, no live-in parents, and no family members running for political office, so we do on occasion get asked "what's it like?"
Well, the SO and I aren't so much into S&M, as B&D. But one person who is into the sado-machocsim side of things (professionally, yet) has a short video up (less than 10 seconds) that pretty much sums up the entire experience nicely.
Earphones in, and not-repeat-NOT work friendly.
