If a guy presses his leg to a girl's leg, tenses up and pulls away a bit, but then he presses his leg to hers again and not move it at all?

I'm confused, what could it mean?
He's my coworker and it was a night out with some other coworkers. We ended up sitting next to each other and I didn't initiate body contact, just sat really close to him but wasn't touching him. His leg touched mine a few times and after sometime he moved it away each time (but he was the one who initiated touching in the first place every time). But after an hour maybe, he pressed his thigh to mine again and didn't move it away for a good 10-15 mins, maybe more. I could feel his leg tensing up a few times during touching for a few seconds but he kept it pressing to me.
I'm confused what it means because usually a guy either pulls away right away which means it was an accident or he doesn't move his leg at all (which means it wasn't an accident) but he pulls away a bit at first but then initiated touching again and didn't move away this time.
Could it mean he's attracted to me or likes me?

It happened before, our knees touched under the table and he didn't move his leg.
