While I was looking for the study I talked about in the previous post, I stumbled across a prospective study where women kept diaries detailing their sexual activity and their pubic hair removal behaviors.... which were then analyzed by the scientists to look for correlations. They found, unsurprisingly, that women who removed their pubic hair tended to be younger and more interested in sex.
Women who chose to remove their public hair were also more likely to engage in fingering and clitoral stimulation with the hands, which suggests a willingness to have more varied sex than their counterparts. Perhaps because of this, the scientists additionally discovered that pubic hair removal was associated with a slight tendency towards a longer duration of vaginal sex. However, as I implied, I suspect that has less to do with the hair removal per se and more to do with who is removing that hair... and who they're choosing to have intercourse with.
