It's always cultural, but it's fashion too. Most of the male models I see in fashion mags and such are clean shaven, and the whole porn look highly shaved deal is very trendy now too. Southern Sorority girls still shave, Berkeley girls, not so much. American's shave more than any other girls, but that was just a way to sell more razor blades.
