My [22F] first ever boyfriend [30M] of 5 months wants to spend every waking moment together and it?s driving me insane

I met Sam at a book club and we hit it off right away. He?s funny, super smart, and we have lots in common. But pretty much from day one we?ve had the issue that he wants to spend WAY more time together than I do. He wants to be together every single evening and every weekend. I?ve told him over and over that I?m not ready to spend that much time together, and that I need time to myself and space to hang out with my friends and engage in solo hobbies, but it?s like talking to a brick wall.
To give you an idea, we spent all of last weekend together. I asked him to leave Sunday afternoon because I had some errands to take care of and wanted a bit of alone time, but he dragged his feet on leaving until well into the evening. We had plans to hang out on Tuesday and Friday. Monday I?m going to hang out with my coworkers, he begs to come along, and I say okay. Then he wants to come spend the night and we argue about it for twenty minutes before he finally goes back to his place, pouting. We hang out Tuesday as planned and he spends the night. Wednesday he surprises me with tickets to a movie I?ve been wanting to see, I go back to his place afterwards, we have sex, and he gets really upset when I leave to go back to my place. He asks to see me the next day, and I tell him really clearly that I?m feeling really burnt out, I need some space, and I don?t want to see him tomorrow.
The next day I?m watching the hockey game with a glass of wine. I used to watch a lot of hockey but haven?t had a chance much lately because he?s not a fan. He starts blowing up my phone asking what I?m up to, I tell him that I?m relaxing and watching the game, he says ?I?ll come over and watch with you!? I said ?Sorry babe, I told you that I want to hang out by myself tonight. We've spent the last week together and I need some me time.? Twenty minutes later, he?s knocking on my door. I told him that I didn?t want to hang out, and he was all like ?I just drove all this way to see you, look, I brought your favourite dessert? and I felt guilty so I let him in. He lasted maybe ten minutes of hockey before asking to watch a movie instead, I said no, he talked incessantly over the commentary and completely ruined the game for me. I got mad at him when he wouldn?t shut up during overtime, and he was all ?It feels like you don?t even want me here, you?re just ignoring me to watch a stupid game? and I said ?I DON?T want you here, I was really ****ing clear about that? and it kind of devolved into a big fight.
He said that I?m immature and afraid of commitment and that normal people WANT to spend all of their time with their SO, and I just don?t understand what?s normal because I?ve never been in a real relationship before. I was too mad to talk it through so I told him to go and he just wouldn?t leave!! I ended up storming out of my own apartment and went to spend the night at a friend?s. We sort of patched things up the next day and he promised to be more respectful of my personal space and apologized for being rude. But then he came over on Saturday and talked me into letting him spend the night, and then took ages to leave yesterday even though I asked him really clearly to be gone by 10 because I had plans, and I?m just feeling really ****ing resentful. How do I make him understand that the way he?s behaving just makes me want to spend less time with him??
tl;dr My boyfriend wants to hang out all the time, I want to hang out some of the time, he gets whiny and pouty and guilt trips me. How do I get him to understand my point of view?
