Bf got upset bc I laid across him

Me(20F) and my bf (21M) just got done showering together and we’re laying on a two sweater couch watching Shameless afterwards. I put my feet up on his lap to lay flat and he gets super upset and moves across the room away from me because he says he doesn’t want my feet on him. Am I wrong because I layed my legs over his?? Also there’s like nothing wrong with my feet lol they’re perfectly normal and freshly clean might I add.
