Is it possible that I can get some mature scientific answers here?

I'm working with a pornstar on a creative project. Not the first time I've had contact with skinflick artistes. But, up until now, they've all been pretty flaky. This woman is a nice, sweet, sharp lady who seems quite sane. She makes videos catering to Belly Punch fetishists, and from the clips I've seen and the correspondence we've had, it's clear that it's not just a job for her. It's her personal kink.

I have personally experienced "Breathtaking Beauty" as a little thing. A moment of longing so intense that the diaphram spasms with the force of a physical blow. Is the fetish an attempt to recapture that experience? Or is it a response to some other drive?

This is someone I respect and I'd like a better handle on where she's coming from.
Update: Before people start climbing all over my case, I'm not asking this here because I think GLBT's are perverts, but because your community, and especially Lesbians strike me as being more mature than most folks about things like this.
Update 2: Thank you Ashley. It's good to know that there are actually knowledgeable people on Y!A. Ignore the guy in the spandex. He followed me here from Poetry.
Update 3: I meant "Literal" not "little" thing. It's just that my thing is little. Freudian slip, I reckon.
