Brief Answer: Allergic skin reaction of the genitals Detailed Answer: Hi, I understand your concern regarding the skin problem and I hope I will be able to help you in the same. Now your friend seems to have few skin lesions over the penile region. First of all, I would like to assure you that since the lesions appeared suddenly and have started to fade out the same day, so it is really rules out any sexually transmitted disease in the first place since none of the STD's tend to heal so early of their own. It would be great if you can click some close up pictures of the skin lesions and upload them here on this page. You can also email the pictures at YYYY@YYYY with heading as ref to Dr Geetika Paul. Going by the description that you have provided, I think these lesions can be more of an allergic reaction. Try to find out if there is history of application of any oil or cream to the region. Hope he has not used any harsh soaps, cleansers or dettol over the region. Sometimes even early fungal infections like candidiasis can show up like small red bumps. I would like to know if there is any history of development of similar lesions in the past. Also whether there is any associated pain, itching or irritation. I am sure that I will be able to help you more once you follow up with the pictures. Waiting for your response, Dr Geetika Paul
