I always figured there would be more people who are older than younger, if only because people become more adventurous as they age. You know, the stereotype of the bored housewife and all.
Also, something I forgot to add to the original post is that I've noticed an awful lot of kink in popular media lately. On the plane back from the UK I picked up a copy Maxim (UK ed) and Tattler (UK Cosmo-like pub), and both contained a couple of BDSM elemnts.
Since these are both very mainstream representations of sexuality, along with other stuff I've picked up, I believe BDSM is in this wierd place in society where everybody knows about it and a lot of people do it but no one talks about it because no one wants to admit, as an individual. Like the way tween/teen girls are supposed to be about masturbation.
Thoughts, anyone?
