Ive noticed an odor coming from my penis when Im aroused and before masturbation.  This has only become apparent in the last two months or so.  It wasnt like this before.My penis isnt circumcised.  I wash it every day, but only give it a thorough washing (by pulling back the foreskin) maybe once or twice a year.What could be causing the odor?
This odor is normal. Nothing to worry. Mat ain hygiene of part. If you are to worried then go for STD test. IF NEGATIVE FORGET ABOUT IT.
