Here's a couple of college girls in their baths who couldn't be more different. 

This girl is slim and cleanly shaven and has the sweetest smile, letting you know she appreciates everything about you, including the size of your cock.

Compare her to ol' sourpuss chunker here, who is intense and driven, needs a shave, and would kill for a fuck.  She doesn't care how big your cock is, she'd beat you up if you don't fuck her, and she's big enough to do that.
