Etching in penis tip

Patient: I’m 26 yrs old & I’m unmarried.Recently from 5-6 days back I’m observing that the foreskin of my penis is itching & it is getting fatty only in one side.When I pull down the foreskin I found some white color oil-like substances accumulating under the foreskin causing a bad smell also.It is accumulating only right side of my penis.I’m still virgin & I never had any sort of diseases in my genital organ.Please suggest what should I do asap.
