I am a 18 year old male. For the past few days, I have been experiencing significant itching and dryness in my private area. Symptoms: There are small red bumps and rough patches on the skin. Crucial Detail: I have noticed that the itching becomes much more intense whenever the area gets warm or sweaty. The skin feels irritated and dry, especially during cold weather, but the 'heat' makes the itching worse. Treatment Tried: I applied  Vaseline before sleeping, but it did not provide any relief from the itching. I have not used any medicated creams yet.
