odour

Hi, i'm 17 years of age, recently had a problem with phimosis which i have sorted luckly.. but i now have a problem with a strange odour i seem to smell, no one has said anything about it (girls with oral) but i cant help but notice it, i am regulary cleaning everymorning, yet still there seems to be a strong smell, when i retract my penis
Wouldn't mind some ideas, as it's mucking up my self esteem:)
cheers
