No rubbers or Vasectomy needed. So before your big date make sure you do these things OK. Eat and drink things with yellow #5 in them. An when taking a bath after eating make sure you rub one out in the tub. When thinking about the Octomom or i let you slide with Kate Gosselin better yet f*ck them both at the same time in your mind when waxing off in the tub of scalding hot bath water. Because just thinking them ladies will jack up the fertility rate of your seamen load your about to bust out in the tub. An then after that your good to go my man, because your going to be shooting blanks all night my man. An take it from me because i have been kid free and STD free since 1993. "She will never miss her period again." it's just science.
