Masturbation is normal, healthy and there is absolutely nothing wrong with it according to the vast majority of doctors, scientists and psychiatrists. I would be far more concerned about anyone who claims they’ve never masturbated. If you are in a relationship and you don’t feel the need - good for you. Not everyone is in that same boat.
