I cannot confirm anything without examination but it can be due to balanitis. It is an inflammation of the glans penis.
Oral course of antibiotics is needed.In addition,pls don’t use any cosmetics on the penis,instead use some topical antimicrobials like Bacitracin or Lotrimin.Also corticosteroids and topical immunosuppressants can be used but they are available under prescription. Also retract the foreskin daily and soak in warm water to clean penis and foreskin.In case the symptoms persist then pls consult a urologist/dermatologist for evaluation and antimicrobials and steroids prescription.
