Is this a disease?

Today I discovered this "point" on my penis. It's bad? I'm 14 years old, don't kidding me, please help me. ( sorry for bad quality of image )

Dunno if it’s a disease. Certainly doesn’t look like one. Are you sexually active?

I had sex in January and I masturbate daily but today I discover that “point”.

If you leave it alone for 2 to 3 weeks it will probably heal itself - try not to masturbate as it could be to do with your grip …
