What am I supposed to think when a guy im friends with is scratching his balls in front of me?

i secretly have a crush on him too and he seems to care about me here and there gives small talk and stuff but he was scratching his balls repeatedly the other day in front of me?
i dont care about a man has gotta do what he has to do, but also isn't it disrespectful like he doesn't care about what i think so he's gonna act like unimpressive around me?
