Am i sending him the wrong message?

on saturday, me and my boyfriend were watching Titanic. he knows i am SUPER obsessed with that movie and that i LOVE Leonardo DiCaprio, so he agreed. we were sitting on the couch, watching it, and he did the old yawn-and-stretch-your-arm-over-the-girl thing, then asked me if it was okay if he did that. i was okay with it, and i said "that was respectful to ask but you don't have to ask me, just do it..." then things were quiet the rest of the night. what should i do? he hasn't been avoiding me or anything, but he hasn't returned any of my text messages or IMs [don't worry, i'm not being needy and sending 100000 texts and IMs. I only sent him one text and 3 IMs] help!
