In 2009, a study led by professor Stuart Brody from western scotland university stated that size did matter. (reference here) 1000 czech women were asked to compare their partner’s penis length to a czech bank note. The bank note measures 14.5 cm (5.8 inches). Based on this measure, they were asked whether they were more or less likely to orgasm with a longer penis, whether length made no difference, or whether they had not had enough experience to judge. 34% said they will likely have an orgasm with a larger than average penis. The rest of women said it didn’t make any difference to them.
