Why did my guy friend randomly block me?

I've been knowing this guy since mid June and things were going well and we talk about random things or send each-other animal insta posts. I did like him and we both were attracted to each-other but he wasn’t ready for a relationship. As expected its college so we stayed as friends but we did exchange sexual photos to each other and we thought about getting experimental physically. We finally got a chance to hangout 2 weeks ago and we goofed around and he made sure I was comfortable were both kinda inexperienced. He guided me through grinding on him because I struggled and then we kissed but I haven’t got the hang of it yet but I did enjoy everything. He taught me how to give him head which resulted him to.. y’know. He cleaned up his mess tho. He also works out and he has a nice build so I go to him for workout advice because I started working out. But upon waking up I noticed that he blocked me. I don’t know why he blocked me if we’re just friends but maybe I took it too far? I mean I tell him jokes every now and then but I don't know. he's a nice sweet goofy guy but I don’t know what I did wrong.
