Hi doc
2 years ago i had unprotected sex , the next day a rash appeared on my penis it covered the whole penis , it was not painful, i went to the doctor, she said it wasnt herpes , but sent me for a blood test after3 months and then again after 6 both returned negative , she prescribed me a steriod cream which cleared it up , the problem is that it keeps re-appearing! i went for another std test which again came back negative, the rash seeems to appear after sex or masturbation infrequentley , it is not painful or uncomfortbale , i went to another doctor who said it was tinea , it is worrying because in the back of my mind i think its herpes but surely 3 blood tests would pick it up, it reacts to cream , or if i roll back the foreskin it seems to "dry up" and dissapear quicker , it can appear in juss one spot or can completly cover the penis , foreskin inside and out at times , i searched on the net and i think it might be scabbies , but could they last this long?
please help
