why would you invite him over to watch movies with you on your couch if your going to be sitting between his legs the whole time- I mean, it's defiantly not that he minds it, but your mute boyfriend wasn't expecting for you to position yourself to sit- not next to him, not on his lap, but between his parted legs, again, he dosent mind and it is basically optimal movie-watching position, but you could have said so he could mentally prepare some, but that's ok- he's good a playing it chill.
