Does my dad just not care?

My dad walked in on me having sex and I didn’t notice it at first bc I was in doggy and he wasn’t saying anything. He like just was standing there kinda outside the room, at the door. I don’t know what he was doing but he left once we were done. My bf didn’t see him but I did once we were through. He didn’t say anything after my bf left either. I’m just confused as all out rn
