I need to ask a qn.. I was fooling around with a guy and he dry hump me wit his underwear and I'm naked. He has pre cum on his underwear when he dry hump me after which later he came on my hip.. We carry on later when he wear a condom and he uses his penis with condom to rub my pussy which he later came again in the condom.. He finger me a lot in the process but I wasn't sure if he has any pre cum or cum on his finger while he finger me .. So what are the chance that I will be pregnant? Do I need to get ec?
