Semen will "dissolve" and just leave it wet mess after a while...
mhmm thats true.
After ejaculation, semen first goes through a clotting process and then becomes more liquid. After 5-10 minutes or maybe more, it will become more watery and liquid before finally drying. All u had was a wet dream no worries.
