It is a commonplace of sexological research that women are supposed to be less easily aroused by visual erotica than are men: this is found in the bulk of relevant research from Kinsey onwards, but some of the findings are ambiguous. Recently various women have been involved in the creation of "pin-up" magazines for women. The two most famous of such magazines are "Viva" and "Playgirl". Are women, suddenly confronted with a graphic centrespread penis fastened onto a handsome male, stimulated to lustful urges? I don't know. The only girl I asked declared that it didn't do much for her but she kept looking!
