Well; the tl,dr of this is simple.

I am almost blind and have no depth perception - so I can't really "see" boobs or butts. And body detail in general.

But, hair sticks out - a lot. So I *actually* see it, and often even use it to recognize people. Thus, I ended up developing a hair fetish. ^^;

If you are down for a rabbit hole... look up "hairjob". ;) Should explain everything.
