Women are more likely to have vaginal orgasm when lover's manhood exceeds 5.8 inches, a new research has revealed
Brody and his colleagues found the women who reported the highest number of vaginal orgasms in the past month were most likely to say that longer was better.
“This might be due at least in part to greater ability of a longer penis to stimulate the entire length of the vagina, and the cervix,” the Daily Mail quoted Brody as telling to Live Science.
The research was printed online in the Journal of Sexual Medicine in September.
