Why do people look at me?

Why do people look and stare at me....I had bad acne but is.getting way better could that be it? Or is because am tall I am 5'11 ? They don't give me a.disgusted look is more of a look at me for few.seconds and look away and look back is mostly girls I M not sure if am ugly or not and if I am I don't care just the staring is what makes me feel so weird what do yall think?
