Different standards?

My husband and I were talking, he said that “if I catch you looking at another dude- I may be uncomfortable and might say something about it but I won’t get upset with you and I’ll move on. He’s a human, big whoop.” So I praised him and said “I love how mature you are, what are your standards with that for yourself?” And he said “of course I’ll notice other humans, but I don’t feel the need nor want to check them out. I have no reason to. I’m entirely yours and entirely in love with you.”. Could it be true he has different standards for me than for himself? Like it’s whatever if I check other people out but he says he truly doesn’t have the interest, if there’s a butt etc. on tv it’s just a butt- nothing more than that because it’s not mine etc. Him and I are together 24/7, he hasn’t watched porn since we’ve been together and I know this bc again- I’m with him ALL the time. (With that being said I wouldn’t necessarily mind if he did) but does it sound like he’s being truthful and this rare chance that he’s a male that truly doesn’t need or want to check out other females or is this just an entire lie?
