there are several theories as to why most of us are right handed, some are left handed and others are mixed handed which is not the same as being ambidextrous. I thought I was a definite right hander until I took the Edinburgh Handedness Test and noticed I’m left handed when it comes to opening boxes and lids.
and then I remembered something else. when it comes to playing with a penis I am ambidextrous with a slight preference for using my left hand.
Neuropsychologist Chris McManus has been researching handedness for decades. He is one of the few scientists to achieve the rather bizarre accomplishment of receiving an Aventis Prize for Science Books and the infamous Ig Noble Prize from Harvard University, both in the same year. the Ig Noble was for a paper about the asymmetry of testicles.
“In most men the right testicle is higher (62.1% or 65.1% according to which survey one cites) and larger than the left, but few are aware that the average weights are 9.95g and 9.36g respectively and 9.69 and 9.10ccs in volume.”
Centuries ago it was believed that male seed came from the right testis and female from the left.
Long after it was influencing how Greek sculptors saw the male body, men were being given extremely uncomfortable-sounding advice on conception. “As late as 1891, Mrs Ida Ellis in her Essentials of Conception stated: ‘It is the male who can progenate a male or a female child at will, by putting an elastic band round the testicle not required’.”
