Thanks for commenting Abigael! The more important difference is knowing the difference between the vagina and the clitoral organ. The clitoris is the female sex organ and clitoral stimulation is required if a woman is to experience orgasm by masturbating alone. The vagina is a reproductive tract that men like to penetrate in line with the reproductive instinct. The vagina has nothing to do with female sexual pleasure. Some women may enjoy emotional rewards from lovemaking especially when they are in love. This ignorance over their own anatomy is clear evidence that female orgasm is nothing like as common as people would like to believe.
