I am no doctor, but I think that those wrinkles in the glans won't really prejudice you. Maybe reduce your sensibility but I can't see how else it could harm you. It might take you longer to have an orgasm, but as long as you can ejaculated and continue your genetic line,i believe you are fine. About removing the scars, I don't see how, but like I said I am not a doctor, so don't trust me 100%.
