Take it for what it's worth,

though I'd be interested to learn a little more more about how "years of experience with a variety of women alerted

him to the finding that sexual prowess differed according to their pubic hairdo."

Personally, I've never

noticed anything other than that the more "inexperienced" a woman, the less likely she is to shave, but I know it

would take a lot more data points than my own experiences to come up with hard and fast rules.
