hymen?

How do I tell if my hymen is intact. I'm worried it's not. I haven't had sex so I know I'm a virgin and i know a broken hymen doesn't mean I'm a virgin or not. But I was wondering if Its intact or not. So how do I tell? I want to bleed my first time i have sex so they KNOW I'm a virgin for a fact. I masturbate (using hairbrush handles and things like that) and used tampons but that's about all I can think of that broke my hymen. But how do I tell. (Don't judge please)
