Help?

So I hung out with a guy I've known since high school last night (I'm 23 now). We agreed that we would kiss to see if we felt anything but I said no to anything more. Well, he kept poking at me and grabbing my arms (I have a few bruises actually) and would squeeze my boobs. I told him to stop but he didn't listen until I yelled to stop. I thought he was just joking around but then he went to kiss me and tried to put my hand on his penis and tried to rub me over my pants and I freaked out and said no again. I didn't want to and he said it was out of habit! I left his house and I've only spoke to him a couple of times since then. I don't know what to do.
