Hello and thanks for your query.
I shall make an effort to provide you with good professional recommendations specific to your questions.
Based on the information or appears to be UTI or
urethritis. Urethritis is the medical terms for inflammation of the urethra, which is a common cause of penile burning sensation.
Cystitis (inflammation of the bladder) or
prostatitis (
prostate inflammation) can also be associated with a burning sensation in the genitals.
I don't think
masturbation is responsible for your symptoms. I will all you to observe for any cuts on the surface.
Treatment is based on the cause, presently I would have suggested you to keep the area clean, drink plenty of water, if possible consider having cranberry juice.
