A rash like irritation that can form on a man's inner leg regions. This irritation formulates due to the man
ejaculating semen and allowing it to pool in their
inner thigh region, thereby causing irritation as they walk around due to the moist
environment and friction.
The irritation or "Cum Rash" clears away after a shower to remove bacteria and adequate drying of the area.
This should not be confused for Semen Allergies.
