Perineal raphe is very prominent. It's always been this way - how do I get rid of it?

I know that this doesn’t affect performance or anything, but if anyone knows how to get rid of it then that would be greatly appreciated.

The perineal raphe, if I remember correctly is something that develops early as babies are developing in the womb - what you have is a natural part of you, you do not “get rid of it”.
Even if you found a surgeon such as a ‘Cosmetic Urologist’ I would advise strongly against it as there are to many instances where these kinds of procedures go wrong and you ended up with unintended consequences.
My suggestion would be: it is a natural part of who you are, live with it and embrace it - to me it would be like someone saying ‘I do not like the little finger on my left hand, I think I may look into getting rid of it’
Not something you do, really
