Pressured into sex?

I just invited one of my guy mates over to my flat to chill. After meeting him at the station, catching up, jokes, etc etc. after about an hour or so, he starts making the moves on me. Putting his arm round me, doing his thing. I didn't really know what was going on at this time, but I had a feeling I knew what he wanted so I just made it clear to him and said "I don't know what you expected when you came here, but THAT is not happening". So he said ok cool cool...carried on talking for a bit. Then he starts getting a little impatient. I think he knew that I meant no when I said. So he really started sort of going for it, feeling me up, he even pushed my head down. I kinda threw him out.

I just kinda need to rant this out, because I don't know who exactly to even tell. We are both 3rd year at uni.

I'm just wondering if when a girl invites a guy over, is it usually a booty call just like that?? Or was I asking for it? Should I have been more clear? I don't really know what's just happened

So its just a usual thing then? Would no guy just come to a girls flat just to hang out?
