I've tried fungal infection medications, hydrocortizone, vaseline, bathing in water with baking soda, tea tree oil, apple cider vinegar, diaper rash
cream, hypoallergenic lotion, vitamin e oil, changing detergents, no sexual contact for
a month, washing thoroughly, sleeping without underwear..
I recently realized that it would get worse whenever the area is wet. So I stopped with the creams since they were only doing me bad, and just dried the area thoroughly when it gets wet.
