(Insert Your Noun Here) Porn

I think the term "porn" is an adjective whose time has cum (yeah, I went there). 

Porn is, as most would see it, something sexy, tantalizing, even forbidden.  As a personal aside, as a class of movies, I've found porn not to do much for me, the longer I watch it, it seems fairly contrived and well, boring, no matter how shocking it gets.  I realize I'm in the minority on this and maybe I haven't been just been exposed to the kind stuff.  But until then, I just don't buy it, and I can't get off on something that doesn't at least seem genuine. 

But I digress, porn can be used as descriptive term, for talking about what you do get off on.  Take, for example, a good masculine jawline on a man, the kind you just want to lick when you see it.  That would be, for all intensive purposes, jaw porn to you.  Let's say you find a really lovely set of hands, long, dexterous, yet strong, maybe that's finger porn.  A particularly red and well formed set of pursed lips - lip porn.  A witty, Good Will Hunting mind?  Brain porn.  Yes, now you've got it. 

What's your favorite kind of porn?
