In a bizarre revelation from a study of 545 straight married couples, every inch of penis length "increased the likelihood of women being involved in extra-marital partnership by almost one-and-half times." so the bigger your dick is, the more likely your wife is to cheat.

We're not sure about Asia, because you'd think the bigger the better, right? But the study was conducted in Kenya:

"Women associated large penises with pain and discomfort during sex which precludes the enjoyment and sexual satisfaction that women are supposed to feel."

In fact, one woman interviewed for the study told the researchers the following: "Some penis may be large yet my vagina is small, when he tries to insert it inside, it hurts so much that I will have to look for another man who has a smaller one [penis] and can do it in a way I can enjoy."

According to the study, 6.2 percent of the 545 females had affairs during the six-month study. Other factors that increased the likelihood of women straying outside the marriage included domestic violence, being denied sex or denied preferred sexual position, being under age of 25 and a lack of sexual satisfaction.

So there you have it. Huge-ass penises aren't all that wonderful after all, unless you have the vagina to accommodate an XXL.
