My boyfriend cummed all over my boobs. Then I spread them with my hands all over my boobs. After we were finished, I wiped the cum off my chest on my jeans and then wiped my hands. 5-10 minutes later, I started feeling myself, forgetting I had cum on my hands. Could the semen on my hands impregnate me? Some say that oxygen kills the semen but its proven to be a myth. I'm not getting ny period for another two weeks. Help:/
