The very last thing you want to think about in relation to sex - your mother.

And here we are about to put both ideas in your brain at once... but it's for the sake of science, fellas.

According to a study published in The Journal of Sexual Medicine, men with "mommy issues" are more likely to suffer with erectile dysfunction than men with healthy relationships with their mothers.

Stuart Brody and Petr Weiss of Charles University in Prague documented 960 Czech men, rating them on erectile dysfunction (ED), premature ejaculation (PE), intravaginal ejaculatory latency time (IELT), the first age they fell in love and the perceived health of their relationship with their mothers.

Men who had poor relationships with their mothers tended to fall in love and get in relationships later in life. Greater intravaginal ejaculatory latency time occurred with men who had healthy erectile function and perceptibly healthy mother-son relationships.

History of homosexual activity was not a factor, according to researchers.

Researchers concluded, "The findings suggest that degrees of ED and PE are often comorbid, and both ED and PE are associated with less favorable early experiences with women."

The study was funded by Berlin Chemie, Menarini Group.
