I'm very open with my online friends ('nilla or not), but I haven't told any of my real life friends yet, so I tend to be a little shy on the subject when it comes up. Before I got into it, I was one of those vanilla people that would occasionally joke around about it. Not in a judgmental way, but I had certain misconceptions due to ignorance. Someone took the time to explain everything to me one time, and after being educated on the subject, I decided that I identified with it. Who knows, maybe if some 'nilla friends get educated on it, they'd want to try it too!
