So me and my bf we’re doing doggy he didn’t cum yet and when he slid out the condom rolled to the tip of it covering the tip , he said he didn’t cum in me and that he started coming when he came out and he got off the bed so it wouldn’t get anywhere near me since I was naked. I cleaned myself after he told me nothing got in me nor did it drip on me we even checked the condom after. Should I take a plan B ? I’m just scared that I can get pregnant from this
