While almost all men wish their penis size were bigger, a recent study, by the University of Kentucky, which polled more than 14, people, found 45 per cent of men actually wanted a longer penis. According to a study published in the Journal of Sexual Medicine, a certain penis size gives women the most vaginal orgasms. Speaking about it, authors of the study wrote that research indicates that women's orgasm during penile—vaginal intercourse is influenced by fitness-related male partner characteristics. They went on to add that penis size, and preference for a longer penis is associated with greater vaginal orgasm consistency.
