I am a teenager. My periods generally start between the 27th to 1st of each month. On the 19th of October, my boyfriend and I got intimate. He had premature ejaculation on his tip, though I remember licking it. I then sat on his penis and he's not quite sure if he had precum on the tip or not, it could've been saliva too. We didn't put it in all the way through, it barely passed the walls of my vagina. There was NO penetration and NOR DID he ejaculate anywhere near my vagina. And we did it for like 10 seconds. He'd urinated an hour before all this happened. IT'S BEEN 4 DAYS NOW AND I AM WORRIED SICK. I DON'T KNOW IF THIS COULD GET ME PREGNANT. I'M UNDER A LOT OF STRESS AND ANXIETY AND I HAVE NO ONE TO TALK TO. I READ ABOUT THIS A LOT AND I'M CONFUSED AS EACH WEBSITE SAYS SOMETHING DIFFERENT. I REALLY NEED THE OPINION OF A PROFESSIONAL.
