Yesterday, my partner and I had some intimate moments when she came over. We are both virgins, and yesterday we did some grinding in underwear, but nothing more. I've been hearing rumors about precum, so I came here to clear that up. There was no actual penetration, but I'm just afraid that something maybe seeped through my underwear. I urinated many times before, and didn't ejaculate at all after urination or during the time we spent together. I'm just worried that she might get pregnant after what happened. It's also been a literal week after her period, so that seems dangerous to me. After reading about this, I am thinking twice about having intimate moments like this again, or least until we are ready.
