Hey guys, this is my first time on MedHelp and I have a quick question that I need answered. Any help that you guys can give will be greatly appreciated. I'm a seventeen year old male. My girlfriend and I had sex without a condom two days ago, and I did not have an orgasm or ejaculate. I didn't come close to having an orgasm, I was only inside of her for two maybe three minutes. I've done research on precum beforehand, and I keep getting mixed signals. The last time I ejaculated before we had sex was the day before, but I urinated afterwords, and even after that. Some people say precum contains sperm all of the time, others say precum doesn't contain sperm at all unless it picks up the ones leftover from the last ejaculation. I believe theory number two, however since I urinated multiple times before we had sex, could there have been any sperm in my precum? We didn't really mean to have sex without a condom either, it just kind of happened. We got into it, there was a lot of touching and rubbing, I pulled out my penis and began rubbing her vagina with it. It just kind of slipped in and we began having sex. Anyways, I'm just a little worried that she might get pregnant. Her period ended about three to four days before this happened, I'm keeping an eye on her and she seems to be doing normal. She's showing no signs of pregnancy. Anyways, any help you guys can give would be great. Also, after we had sex (without finishing) I decided to pull it out and stop in the middle of it. We laid on her couch together for another few hours, but when we stood up to leave her house we both got very lightheaded and dizzy, our stomach region was feeling very tingly aswell. Does anyone know what that is, or even why it happened? Thanks for your answers in advance.
