Me and a woman had sexual interaction yesterday. I had boxers, gym shorts, and a condom on. She was fully naked. We were dry humping facing each other and my private areas may have rubbed against her vaginal area for a few thrust. I know I did not finish on her as I was intentional not to. After I got done - we finished with me on top of her on her backside - I noticed the condom had tore. I do not know at what point the condom tore. Do you have an idea of pregnancy risk? Should we get Plan B?
