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.".
