He manhandles me what does this mean?

BEFORE ANYONE SAYS ANYTHING BAD
By manhandling I mean when we're playfighting, wrestling for fun, etc etc. He's a kickboxer of 8 years, and he takes pride in that. However I'll steal his stuff (ie; nerf gun. for fun!) or tease him or wrestle with him. He likes to put me in grabs or headlocks, or subdue me through other physical means, he's very physical with me. However, I don't know what this means because when I ask him if he likes me (once a year ago and once 6 months ago) over text, he won't say it outright, just that "It seems rude to just say it, you know?", but it's definitely a no. So why would he do this? I've never really noticed him do it with anyone else.
