I was going to ask what type of BDSM Documentary you were going for.
I read in the Introduction thread that you are looking to view it through the eyes of a Vanilla transitioning into this lifestyle.
I have seen many documentaries on the lifestyle pertaining to the hows and whys of what people do and why they do it.

It would be an interesting perspective on understanding the mindset of someone who has discovered and wants to embrace that part of themselves.
And of course there are many different types and experiences you can touch upon.

Covering a person's journey would give others a better understanding of what goes on. Just my opinion though.

I for one know that since I have discovered this part of myself, (and while I embrace it and continue to learn about it), I find that is has been one of the most loneliest, tumultuous, and confusing times in my life. Just trying to work through issues as to the hows and whys are complicated at times.
