on the 2nd or 3rd date I had with my wife she told me she worked part time as a nude artists model, one or two evenings a week. I got turned on immediately.
A couple months into our relationship I sat in on one of her modeling sessions, in a private art studio with about a dozen artists, all of them intently studying every inch of her naked body. I was never so turned on before.
I think that's when I got hooked.
