Most Helpful Guy
Um... never? I cannot have children. My life would literally be over. There is nothing i fear more than getting a partner pregnant. I'm just really paranoid, so i wouldn't even have sex unless she is on birth control I'm wearing a condom, and I'm even gonna try and pull out.
I need three lines of defense. However if i had a vasectomy (which i might get), or if she got her tubes tied, then I'd stop wearing condoms as soon as we got tested.
