When my first child was conceived my wife was on the pill. When my second child was conceived she was on the pill AND I was wearing condoms. Judging by her reaction I would say there is NO chance of her missing them accidentally or intentionally. Weren't we responsible?
Again you guys are coming a beautiful act of making love to dangerous and immoral things like firing guns into a crowd or drunk driving. Other than taking a shit, sex is one the most natural things in nature. Yes there are consequences but some people are not fit to handle those consequences...even if they want to be.
