What does it mean when a guy keeps staring at my butt?

there’s this boy at my school, no matter what i’m wearing, he’s always looking down at my butt. no matter what i’m wearing, he never stops. i’ve tried to show him i’m not interested. it started when i wore spandex one day during gym and then he kept looking at my butt and i had to keep pulling my spandex down and my shirt down to make sure. i thought i was flashing lmao. now like i’m at the point where i’m wearing leggings and an oversized shirt everyday. i’m so self conscious and i’m constantly tugging my shirt down every second because i feel like more people are starting to look as well. someone give me advice?

also, i’m too shy to go up to him. i’m really not the best with talking.
