A few hours ago, my boyfriend and I were in his car and he went down on me for the first time. He was using his mouth and then inserting his fingers into me deeply. I was completely naked, and he was just in his boxers. We've never had sex - I'm still a virgin. I then also went down on him (we kind of 69-ed) , but now I'm worried that maybe some semen or pre-ejaculate got on his fingers while he was taking his penis out. He fingered me pretty deeply afterwards, definitely touched my cervix, and I'm just worried that I could get pregnant from this? If he had anything on his fingers, rather. I have a morning-after pill- should I take it? Am I at risk for pregnancy from this?
