The research was conducted by American researchers in conjunction with their Kenyan counterparts. They did so by fixating on the member and putting up hard evidence about the rises and flops of having an endowed member.
What the research found was that women married to men with extra inches were more inclined to cheating on their partners. “Surprisingly, [having a] spouse [with a] longer fully erect penis was associated with increased likelihood of the women having extra-marital partnerships.
From these results, every one inch longer penis increased the likelihood of women being involved in extra-marital partnership by almost one-and-half times,” the researchers wrote. This is apparently because a longer penis increases sexual discomfort. “…some penises 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”.
