Why do females keep staring at me, worried

How do I know if they are staring at me for something bad? Like an orange booger hanging out of my nose? I know for sure I am not ugly though. It might just be because I am half persian, half cajun, so they are curious because I look unusual. They stare for maybe 5 seconds but don't look mad or scared, they just have a straight blank face, or mouth hanging open.:um

What is your hypothesis?
