I have a red rash on the head of my penis that comes and goes. I have no pain during urination nor any itchiness, excepting for occasionally. I have shown it to a dermatologist and his response was that it isn t herpes or genital warts . He prescribed an anti-fungal cream that suppressed the rash for a while but it popped up again right after sex. The red spots aren t constant in location either. I have been tested for syphilis and HIV and tests came back negative
HI, Thanks for your query. As your Dermatologist told this does not seem to be herpes or genital warts and as your tests for Syphilis and HIV were negative you just forget about these diseases.  It could most probably due to yeast infection or may be due to some irritants like condoms (latex or due to lubricants), soaps or other topical applications. If it is not adequately treated a yeast infection, it may recur. Then your sexual partners are not treated for the same then also you may likely to have the recurrences. So take your sex partner also to your physician and treat her, then you will be alright totally. Get well soon.  Chat Doctor. Morgan
