My boyfriend (M23) playfully teases me (F21)?

I've been seeing this guy for a few months now, and he's always been incredibly sweet. He goes out of his way for me, showers me with compliments, and makes me feel special—essentially the ideal boyfriend. We've never had an argument, and our communication about any concerns has been great. However, there's been something concerning lately that I've hesitated to bring up with him. It started a few days ago when he kept playfully slapping my leg. Then, he did this thing where he shaped his hand like a claw and slammed it down on my thigh. It was painful, and I felt like it could leave bruises. I had to ask him to stop about three times. A day or two later, while we were drinking with friends, he removed the rubber tips from my crutches and threw them at me—keeping in mind that I have a broken foot and he has been helping me a lot. The hard tips hit my face and upper body, which wasn't pleasant at all. I jokingly asked, "Why do you like hurting me?" but he just walked away. Today, while we were sitting on the couch, he charged into me, and my side hit the wooden frame beneath the cushion. My ribs still hurt from it. When I told him it hurt, he replied with, "What are you going to do about it?" I said, "I guess just be in pain." Then he went to grab our food. When he dropped me off at home, he playfully punched my arm, and we went back and forth for a bit until he stopped. I'm feeling unsure about the whole situation. I don't want to be overdramatic, but I never imagined he could be physically aggressive. I’ve been in a physically abusive relationship before, and I'm worried about the similarities in how those situations started. I could use a second opinion on this.
