So...sperm is made by bone marrow, now?
No, sperm is made by Jebus, and spilling said sperm, or even worse, discharging it into the orifices of another man, even a Bulgarian sailor with an ass that won't quit and the sort of chest hair you could spend an entire weekend running your fingers through, is a mortal sin and you'll burn in hell forever for doing it while devils poke out your eyes with salad forks. Big salad forks, like the ones they give you at Outback for the buffet. What, they don't sell Bibles near where you live?
