Hi I have a very serious question and I am extremely worried for some reason. Me and my girlfriend are pretty young (17) and we love each other. We've been very intimate and sexual. We haven't done intercourse but have done foreplay and'grinding'. We grind often without condoms or clothes. She hasn't been pregnant yet. Ive read chances are slim but for some reason I'm really worried. Can someone please tell me what the chances are or if I'm overly dramatic. Pleasse be serious I appreciate it.

Well that largely depends on whether you ejaculate or not. If it's just precum, then the likely hood of her getting pregnant are slim. Studies have shown that precum contains little to no sperm. It is unlikely but it's possible with precum. However, since you do not have intercourse, the chances are much lower.

but for some reason im really worried..

If it worries you STOP.

While I agree the chances are slim, they aren't 100%.
