Urology/white flat spots on my boyfriend penis


back side

newer spots
newer spots  
Two or three months ago my boyfriend noticed that he has some really small (pen like) white/flesh absolutely flat-skin spots on his penis. (since that we had sex only once) Many were on the back side of his penis and only a few on the front side... Now those on the back side look like they have expanded ( and connected? ) and more appeared on the front side ( still very small, like the ones on the back side used to look...) Worried that it may be HPV he start using Aciklovir ( almost 3 weeks ago) in hope to stop the spreading of the virus, but nothing changed for better... Those pictures that I'am sending you are after using aciklovir for 10 days or so... what do you think it looks like and what type of testing he can do to find out what is the problem and if it's some STI. Also... should I do some testings too?

Looking forward for your reply

Sorry, but we are not permitted to give specific advice or diagnoses on this forum; just answer general questions. In addition, it would be extremely unreliable and possibly even dangerous to try and make a diagnosis and suggest treatment based only on a brief description and/or a picture, particularly of a skin lesion on the penis or male genitalia.
Most of the time, skin lesions on the male genitals are quite benign with cysts, allergic reactions and infections like yeast or Herpes being the most common findings.  Sexually transmitted diseases can also cause visible skin lesions.  That is why we recommend that you contact your regular physician or consult a local dermatologist as they are the most experienced experts in skin problems of the male genitalia.
