So this guy and I had sex. We didn’t use protection But I am on birth control. Usually he ejaculates on me. Well, this particular time I didn’t feel when he did it because usually it’s a little warm. I didn’t feel anything warm on me. (The whole time I’m blindfolded and handcuffed). Well, once we got done we were just talking and he randomly says “You’re gonna have my kids.” I am on birth control but I’m still kind of scared. So should I or should I not be concerned?
