Is it a bad thing if my boyfriend has told me multiple times if a video game character is hot, as in 'she's got a nice ass'?

He's seen video game females and will say, 'i have to say she's got a NICE ass' or 'oh yeah, I got a good look at her ass' and I questioned him about it but he says it was a joke. He said before when I got really nervous about cheating and him checking out other girls that he doesn't really feel and emotional connection with other girls while in a relationship but also that he doesn't really feel personally attracted to other women when he's with me. I don't know if that just applies to real life women or if he really is joking and thought I'd find it funny and agree. He says he only feels sexual to me and others dont interest him. There's a bit more but maybe not needed to say so ill leave it at that.

Its just annoying to ke and I dont want to be a crazy person thinking its cheating since he's already said that he's just acknowledging that he didn't notice a video game character was attractive like that or that its funny that a virtual character is built nicely. I just can't get it out of my head, if he looks at fiction like that then how do I know what he does for real women? Its like a cat in a video game is still cute even if it isn't real because its still depicting a real thing.
