In this short YouTube segment, Dr. Anne Truong MD challenges the common male belief that an 8–9 inch penis is the ideal. She explains that such lengths fall within the top 0.5–1 % of the male population, making them far from normal. Truong cites a study of women’s vibrator purchases, which shows that the most commonly bought and enjoyed size is 5.5 inches. She links this preference to female anatomy: the vaginal canal has a limited length, and a penis longer than that can press against the cervix, causing discomfort. The overall message is that bigger is not necessarily better for sexual comfort, and the realistic average size aligns more closely with women’s preferences.

Most men think that they should be 8, 9 inches. That's more like, fuck. That's not normal. 8, 9 inches, it's really more the top 1% or 0.5%. And to tell you honestly, there's a study that looked at women, what size vibrator women get. Guess what size vibrator that women buy the most? What size vibrator that women enjoy and buy the most? 5.5 inches. So if you're long, 8, 9 inches, it may be uncomfortable for the woman. Because the vaginal canal can be only a certain length. So the longer you are, you're going to be hitting against her cervix, which is the opening of her uterus. You're going to be hitting against it. It may cause her discomfort. OK? So not necessarily longer or bigger is women want sometimes.
