I was tested in July for stds and I came back clean. I had sex with my now ex boyfriend, who was also clean. I recently had sex with someone new, and I’m a little scared I’ve caught something. There was a condom but it wasn’t on all the way, just on his “tip” and he didn’t ejaculate. But Monday night I had found out the condom slipped off and was left inside me, I got it out thankfully. But I’m still scared I caught something.
