Excessive Masturbation leads to Erectile Dysfunction?

Patient: I’m 21 years old. I’ve been masturbating excessively for the past 10 years by rubbing my penis on the bed. It sometimes goes up to more than 10 times a day. Lately, I was involved in my first sexual intercourse but could not get an erection. The penis used get soft within seconds of erection. Please help me treat this problem. I’m not obese. Also, I quit cigarette smoking since 2 months.
