How to get someone to stop staring?

Anonymous
seriously it’s disgusting the security guard at my school continuously stares and checks me out like a peace of meat I find it really disturbing and kind of like harassment he just won’t look away… it’s like he thinks he has a chance with me or something even my friends notice what he’s doing… how do I make it stop? I don’t know what to do I really want to tell him to stop staring firmly but then again I m scared should I go to a teacher?
