Is my messed up?

Okay so i masturbated since i was 12, im 16, i used soap, shampoo, i tried toothpaste, everything, one time it started hurting but i kept going, now i got a little dot that looks like a birthmark (i think it was a scab that didnt heal) and theres a kinda small lil ring around my that is brown and i think its from too hard. Is this like really bad?
