Basically when the girl moved her body from me (cowgirl sex), I realized that the semen/cum was not in the
reservoir. However, my penis head was indeed covered, and it doesn't look abnormal other than no semen in the reservoir, at least from my angle. I couldn't fully take a look at it cuz I was lying on the bed. Then, when the girl removed the condom and held the base of it, I caught a glimpse of it, and it seemed like the semen/cum went back to the condom tip.
