To summarise "Wide Vagina", it is a theory which explains women's dominance over males in the arena of sexual encounter stories. For many men, great embarassment and shame comes from being labelled as a man with a small penis. Now while this may be true for some men, it is often used by a female as a cover story for the poor quality of the sex, the real reason of course being her exceptionally wide vagina.
To conclude, if so many men are heard to have a "small penis", then why aren't as many women held to have a "wide vagina." Think it through logically, the numbers should be even!
