Like the others have said, it's your body and therefore your decision. You're old enough, both legally and in terms of maturity, to make this kind of decision, so if it's what you really want to do then you shouldn't let someone else's opinion stop you. I know it must be frustrating not to have his support in this, but you don't actually need his permission. If you're sure this is something you want to be a part of you for the rest of your life, then go for it.
