Sir, I Am Feeling A Burning Sensation On The Left

Sir, I am feeling a burning sensation on the left side of the upper skin of glans when it gets rubbed with my underwear or when I manually touch it with my hand. After rubbing it for 2-3 times it goes, but after1-2 minutes, I feel the same burning sensation when it gets rubbed. I masturbate daily and sometimes masturbate face down ( Rubbing penis against bed). Please help me sir.
