Is Having Small, Loose White Piece Of Skin Like Flap On Frenulum Normal?

Hi, I have a small loose white piece of skin, like a skin flap, on my frenulum. It's been there for a while but haven't thought much of it as it doesn't hurt, it's not red and it hasn't seemed to grow, though it may have done slightly, I just couldn't say. It doesn't hurt in the slightest during sex or when I pull my foreskin back. I have regular sex with my girlfriend, and havent had multiple partners. I just know its there. Is this just quite normal? Can if be removed, or will it just heal itself in time? Thank you.
