Farthest projected
ejaculation

Timgad, Erotic Mosaic, late First Century.
This, we may assume, is yet another one for a future Sex Olympics.
Considering the amount of masturbation that goes on there must be
considerable volume of semen discharged in the absence of a
convenient vaginal receptacle. The distances the seminal fluid
achieves before being arrested in flight must surely vary. I have
seen very little documentation on this. Van de Velde notes that the
"rhythmic spasms of ejaculation fling forth the semen from the
external orifice with an impetus which may be perceived if the
emission takes place in vacuo." He adds, with the air of the true
scientist, that the "seminal stream usually covers a distance of
from 15 to 20 cm., but has been known to exceed 1m.".
