Masturbation always was and always will be an undervalued performance art. It's not just about toying with your woo-woo (assuming you have one) or closing your eyes and fantasizing dreamily about a black, broad shouldered stud named Leroy. There's way more to it than that, but mere words cannot do justice to an exquisite art form. You have to see if for yourself (like this movie) in order to appreciate those moments of a woman getting herself off. Then, again, if you had done it for her she wouldn't be taking matters into her own hand. But that's your problem.
