I recently had sex with my girlfriend and while putting the condom on for the first time (while pinching the head of it to leave space for the ejaculation) we realized after three seconds that it was inside out due to the fact that it didnt roll down at all. We then flipped it the right way, rolled it on properly, and began to have sex. Is there any shot that if there was any precum on the head of my penis she could get pregnant from it touching the outside of the condom?
Dear patient. Greetings from Chat Doctor !!!  I am Chat Doctor and shall be answering your question. I can understand your anxiety in regard to pre-cum soiling of the condom head leading to a pregnancy. Furthermore, I will try my best to answer your question and guide you through it. Technically pre-cum is secreted by the bulbourethral glands with some contribution from the Cowper glands. It may contain some amount of spermatozoa. In your case there is a theoretical possibility that the pre-cum may have contained your spermatozoa. They can enter your partners' vagina during the intercourse and lead to fertilization of the ovum leading to a pregnant stage. I cannot quantify the chance of her getting pregnant from such a soiling of the condom. I would recommend you to have a urine pregnancy done for her to be sure. I hope this helps you out. If you have any more questions, please do not hesitate to write back to me. Yours sincerely, ChatDoctor.
