Before laying out my story, please forgive my stupidity and ignorance, I know I'm an id**t, a complete id**t. Now, to the story: After my gf's period ended, we had unprotected sex with surface penetration for a few minutes, not a deep one, without ejaculation. As far as I know, precum does not contain sperm, or if it contains, it contains very small amounts. I did not ejaculate prior to intercourse. The most I'm worried about is the following thing: after 3 to 5 days after those episodes, from what I can remember, we were foreplaying, and I stuck it in her 1-2 times for 2-3 seconds and then took it out, the problem is that I ejaculated 1 or 2 hours prior to this. From what I remember the were next to none amounts of precum, plus she did not secrete any of her lubrication so I assume the environment remained hostile to the sperm that MIGHT have gotten inside. What are the chances of pregnancy ? Her menstrual cycles are quite irregular and that does not help at all..... and we've both been stressing about this for the last few days, thus maybe delaying her period, not helping our cause at all.
