I tend to like a few different body types. One is the fitness body type. You can tell that they work out, and you can see their muscles working when they fuck. Rachel Starr is the best in this category, along with Cherokee and Susana Spears (no hardcore, but she's still hot as fuck).
Another is the really curvy body type. Big boobs, big tits, big hips. Best for me in this category is Gianna Michaels, followed by Alexis Texas, Olivia O'Lovely and Sara Jay.
Lastly, I like girls with skinnier, more petite frames. Lily Thai, Lela Star, Naomi Russell, Lexi Diamond, and most of all, Victoria Rae Black.
If I had to pick one to win though, it would probably be Rachel Starr.
