Is it normal that my bf is punishing me by not wanting to be around me?

So we just went to the gym. And as we were walking out the door, I happened to look next to the trash and seen what I thought was a homeless woman showing her ass while laying on the floor next to the trash. Me and my bf looked at each other like wtf?! And I happened to look again and we were walking towards our car and my bf kept staring to but for some reason he gave me shit for looking back at her and laughing about it. He is giving me the hot shoulders and is being so insecure about ME looking at a crackhead half naked on the floor. I even had to tell my bf to stop staring because he kept looking and he is saying that it wasn’t a woman it was a man. And he’s assuming that I liked what I saw because I thought it was funny. Man now he’s sleeping in the other room pissed of at me.... calling me a hoebag and that’s how he knows I’m a slut.
Fml is his normal behavior ? I’m I wrong for taking a second look at what I saw? FML everything I do makes me a hoe and I’m no were near being one..
