Hi, I've Had Sex With My Partner For The Past

Hi, I've had sex with my partner for the past month now, and I've noticed nothing going on down there. I always clean up afterwards. Anyways, I had sex with her, and I didn't clean up until 10 minutes later. Her fluids were on me, and when I cleaned it, it looked like dry skin, but it wasn't peeling off my penis. What could it be? She hasn't been with anyone else but me, and I never had this happen before.
