I had a friend who was very interested in sex - in the act as well as in the study of it on a personal level. Enjoying it, learning tricks, learning kinks. Said once she would be interested in doing sex ed - something that doesn't exist our, comparatively rural part of Russia, but something she might find in Germany, where she was aiming the whole time.
I asked her a few times: why wouldn't she do striptease or porn? She was eager to do both with her man, after all. She wasn't interested. My guess is - it's the publicity part that scared her off: she didn't want people to think of her as a slut. Otherwise, I think she would've made quite a career doing something she loves.
She was a happy kinda girl, now that I think of it.
