I know how it works and i have educated my self TRUST ME but my bf and i have NOT had sex yet but like he has rubbed his dick down there ... (sorry tmi) but i know that u can tell when a guy comes but there is pre come... and sperm can still crawl up in if it’s in that general area down there. I’ve noticed that my boobs have gotten tender and i have had discharge but w a ting of brown. I’ve heard that’s called implantation bleeding. ... I JUST REALLY NEED HELP AND ANSWERS I DO NOT WANT TO BE PREGNANT.
