Porn Star Dani Woodward

Megan Fox, Stevie, Ginger Jolie, Alessandra Ambrosio.

I suppose I should answer my own poll so here goes...

The 1st String line-up:

Mainstream: Angelina Jolie - I don't care how many kids she has, I still want to do her.
Porn Star: Taylor Wane - The perfect PSE.
Glamour/non-nude Model: Dana Hamm - Angie but with bigger tits and lips.
Nude Model: Kayden Kross - she's crossed over into porn, but I believe she's primarily known as a nude model.

and the Back-ups:

Mainstream: Catherine Bell
Porn Star: Devon Michaels
Glamour/non-nude Model: Denise Milani
Nude Model: Veronika Zemanova

Mainstream : Angelina Jolie.  We all know she's a freak.

Porn Star : Kira Kener.  I've always gotten these vibes that she's not that into sex, but MY GOD what a body.  I've seen her dance and have had the pleasure of feeling her up.  If she ever decides to provide, I will happily empty my 401k on her, even if she just lays there.

Nude Model : Aria Giovanni.  An absolute babe, great proportions, nice "lips".  

Non-nude : Does Vida count?  yeah she did playboy, but nude is not her thing.  If she doesn't count, I would still jump all over tyra.

Salma Hayek
Tia Bella
Aria Giovanni
Adriana Lima

I would have to go with...
Salma Hayek (who out there can think of the strip scene in "From Duck Til Dawn" and not get an instant hard-on?),
Stormy Daniels (among a huge wishlist that will never happen),
Erica Campbell (before she found the Lord), and
"the body" Heidi Klum.  I am pretty sure I could die a happy man after that!
