1. Beginning of friction burn
In the early stage of a genital friction burn, you might notice only a slight redness on the skin. However, the stinging or burning feeling can be much more intense than how it looks.

2. Genital Friction burn blister.
Blisters aren't very common, but they can happen. Remember that they usually pop up more from friction burns on regular skin than on the thinner skin in the genital area.


3. Healing friction burn
The redness from friction burns in the genital area usually goes away in about a week and won’t leave any scars.


4. Infected friction burn
Sometimes, if a burn is pretty severe, it can get infected. When that happens, it might take some time and antibiotics to heal.
