Is this normal? Please answer

I have had this for the majority of my teenage life and I dont know if its normal, at the opening of my urethra I have like a growth? I have seen other people have similiar things but my one always have a different colour than my actual head of penis and doesnt look right, it doesnt hurt or anything but it affects my confidence
Anyone know how to reduce it or get rid of it?
thank you in advance

i also may like to add but normally after masturbation and when I have an erection it looks more prominent than in pictures

It would be best for you to get a professional medical opinion on this as it is possible you have a problem causing this.
Contact your own GP / Family Doctor or if you live in the UK you can also go to a GUM Clinic, most of these are based at general hospitals or in city centres - search " GUM Clinic near Me "
