I think there is such thing, but I'm not 100% sure. I got pregnant & was really surprised. Because I pushed him off a few times, so we didn't really have sex if you say & I never knew he ejected and we didn't use protection. If you add the times up together it was probably 2 minutes or so & I have realized you can get pregnant really quick & easy while most people don't realize that. This was with a one night stand too who I met at the beach. I had an abortion at 18 & do not encourage you to do so if you are pregnant. It will do huge damage to your mental, physical, spiritual & emotional state! And if you aren't pregnant, you should thank God and be abstinent. Which is hard, but you can do because I'm living proof & I was a wild one!
