"Natural contraception" does NOT work!! Please understand this. It's a simple fact.

Off topic, we know. There is another thread about this that will not die. Hopefully people read this, but never respond and also stop responding to the other thread. Both threads should end. Here it is, in plain and unambiguous speech.
A man that has had a vasectomy is NOT a contraceptive. If that man has sex with your wife before you do, his ejaculate will NOT block your sperm. Plain and simple...no, it will not.
There is a 5 page thread about this that will not die. It does not work. Science does NOT support this idea at all. Sperm competes my swimming faster. Ejaculate is there to protect sperm from vaginal fluids, not to kill someone else's sperm. Vaginal fluids are there to kill most everything, and will definitely kill sperm. This other man is essentially adding additional protection for your sperm. It's biology. Please!!!!!........don't consider trying this as a method of contraception unless your goal is to have a baby.
It's a terrible idea.

Never even thought about that.
