It all started a month ago when I do sex without condom it's my 16th time but this time the things are different than before this time sex leads me to different state because this time I felt my forehead skin tear off it leads to red spots on forehead joint and after 5or6 days red spots become red rash. It pains allot when the skin go backside it's like a burning pain. I go to doctor who gave me some medications and said to me to wash it with like warm water plus dettol and then apply ointment tube but I doesn't saw a single percentage result. I am scared and worried about this I don't know what to do and how. Please help!
