I have read that iIf a male is sat upright on the edge of a sofa or chair masturbating there is a chance that he will become unaware of the pressure from the chair building up on the area between his anus and scrotum as a result of the pleasure experienced from the masturbatory act. If the male ejaculates in this position that pressure will result in his ejaculatory muscles tearing due to the pressure obstructing the free movement of these muscles.
Is this true? Has anyone ever sat upright and masturbated in this fashion before?
