Watch: Study Finds Having A Big Penis Can Hurt Your Relationship

Having a partner that is well-endowed may have many upsides, but researchers from the US and Kenya have found that men with larger penises are more likely to be cheated on by their wives.

The study published in the journal PLOS One, looked at extra-marital affairs of women married to fishermen living along Lake Victoria in Kisumu County, Kenya.

The study’s findings showed that women were more likely to cheat on husbands who had longer penises, and that size correlated to cheating risk.

“Domestic violence, denial of a preferred sex positions, longer erect penis, younger age and increased sexual satisfaction were the main predictors of women’s involvement in extra-marital partnerships,” they wrote.

“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.

“Similarly, our qualitative data also support this finding. Women associated large penises with pain and discomfort during sex which precludes the enjoyment and sexual satisfaction that women are supposed to feel.”
