Clingy

So I just recently started seeing this guy, he's two years younger than me.. I've noticed hes super clingy and touchy! I really don't like it... I've told him a few times to not touch me certain ways. Am I being rude? And if doesn't help that he's super unexperienced with relationships. I guess I'm just not used to it. He is super sweet though but lately I just feel like running from him. 😱
