slap your mother?
Dick size is a trait inherited from your mother not your father. Forgot where I read this, but as far as I can remember it was a legitimate site. Ooops, or maybe not…
According to the National Center for Genome Research at the National Institutes of Health, penis size, like height, weight, and general build, probably comes from both mother and father. Research on size-related genital genetics is scarce because funds and brain power are, understandably, spent on finding treatments and cures for genetic disorders, like human growth hormone deficiency, which can cause stunted penile development.
