So, me and my boyfriend have had sex multiple times. We have been together 5 months. We almost always use a condom, but today we didn't. He put it in, and then when he was about to cum he pulled out ad cummed on my belly, them put it directly in. I don't know when my period is due, nor do I know if I'm ovulating. Could I get pregnant from him not wiping his dick off before reentering?
