Petite girls don’t always have petite pussies, just like big girls don’t always have big ones.
I have certainly had sex with women who were looser and others who were snugger (sometimes to the point of being a bit too tight). They all felt good. Like most guys, I would prefer tight without being distractingly so, but I can’t imagine passing on having sex with a woman I otherwise found desirable just because she was on the looser side.
