Silent treatment after hook up?

Anonymous
Recently a guy initiated contact with me on a dating site. We quickly discovered we had gone to the same school. He suggested we text rather than email back and forth. In the middle of texting he called and we talked for 2 1/2 hours. Two days later he asked if he could meet with me. Again we talk for over 2 hours. Two days after that I suggested we get together, which ended up being another two days after that. Deciding what we were going to do, we both admitted physical attraction to the other...yet agreed that neither wants any kind of commitment. We ended up meeting at his house, and "hooked up" three times during the course of that day. I left really late, when I got home he texted me saying he had a lot of fun and wished I could have stayed longer. The next morning I texted him about something funny that happened and we joked about it for about 30 minutes. Ever since then (been 2 days ago) I've sent him two different texts which have not been responded to.

Does this make sense to anyone else, because I am nothing but baffled. Up until the "silent treatment" we were getting along almost perfectly. What gives? And should I just call him and ask for an answer, or wait it out and see what happens?
