Your misunderstanding of the Catholic teachings on marital sex and marriage are, to be blunt, utterly flawed. A Catholic who would be putting a spouse at deadly risk by having sex, but who is forbidden to use contraceptive devices under authority of Catholic teachings, is rather obviously not called to marriage in the first place.
Also, your tone is snide and childish, and has no place in grown-up discussion. If you can’t be civil in your viewpoints, please don’t let the front door hit you on the backside on your way out. We who are interested in polite conversation have little time to waste on unequivocal and unintelligent r**udeness **such as this.
