White substance on the penile head, did not have sex or masturbation for a long term. What could be the cause?

Hi, my name is Dan, I recently stop masturbation cold turkey been going just over a month now, I exercise alot and have not had sex in the past 9 months maybe longer, I don t drink, however last night I went out to a party and drank a few beers for first time in 4 years. I went to have a shower today and I noticed a white substance surrounding the head of my penis , I just took a shower got a fresh cloth and soup and whipped it off and cleaned it. I really need to know if its anything serious. I m worried because I haven t masturbated so no strain on my penis and I haven t had sex in 9 months so I don t understand whats going on or if its something I need to be concerned about , the substances didn t feel like semen
