So today me and boyfriend were in the car and I sucked his dick and he cumed but in my mouth and I spit the cum out and then we kissed after that. The he went to the bathroom and he urinated. Then he came back and eat me out and then he rubbed his cock on my Vigina and we don't know if he pre cum while he was being rubbed in me so I took plan b about an hour or more after and the real question is , am I pregnant ?
