Boyfriend Help- very clingy boyfriend

Today I told him I was gonna have to kick him out because I had to get ready for work and he wanted one last kiss, which is fine, but it turned into him making out with me and grinding on me and it's like dude, I don't want this and I've voiced it on multiple occasions that that's not my thing all the time. I'm a very relaxed person and it just bothers me and feels kind of rapey sometimes. Especially when I keep pulling away or make small gestures to stop. It's like he doesn't get it and now he thinks I just don't want to be in a relationship or don't like him. I love him very much and I just don't know how to tell him that I don't care for that all the time without sounding like a bitch or someone who doesn't want there to be action in the bedroom. 

I just don't know what to do anymore...
