Basically, today, I realised this guy at my swim class who's like 7 years older then me has been watching me get changed, I find it disgusting. I want to know why guys do it. It's freaky. The guy is single, obviously, and perved on my friends and siblings. It's weird as. I totally freaked out and cried so much. Overreaction I know, but knowing he's seen me naked makes me feel like a slut. I'm so scared he's taken pictures or something. Help?
