This past weekend was the first time my girlfriend and I had had sex, and my first time ever, and we did not use a condom for probably a half hour or so at least. She came three times during that period, and then we switched up positions and she put a condom on me so I could cum too. In any case, I was wondering how dangerous this really is. Her period is supposed to be in about a week but i'm just worried about whether our actions were really that dangerous as far as pregnancy is concerned. I'm 20 years old and have a hell of a lot to lose, as I will get kicked out of school if my girlfriend gets pregnant. We did this twice more before the weekend was over, but I never came unless I was wearing a condom or when I got relatively close she would start giving me head until I came. Any help would be greatly appreciated. Thank you.
