Dating advice

Dating advice I’m m21 and I’ve never really been in a relationship. Im a custodian and I really like this para teacher at my work. She’s really pretty and kind to me and gives me compliments sometimes and I give her compliments too. i stutter around her but I manage it and can play it off most of the time but when I try to ask her out I stutter so I give up. Anyone have any advice on what I should do?
