Looking for advice- update

Is there such a thing as a man who doesnt have to sneak away 2-3 times a day to look at models on his phone.

Like even if he didn't sneak away to do it...

Is this a forever thing that I just have to accept as part of life? I'm tired of knowing that's why he was in the washroom for 30 minutes. I wish I was okay with it and it didn't bother me but I can't seem to get over it. And then I think maybe it's all men and all relationships that need that external novelty for their eyes. I know I obviously am not the only woman he finds attractive, but the every day on the phone seems so extra and also unavoidable.

Sorry if my thoughts are everywhere. I try to talk to him about it so that at least he can tell me its okay. He always just says that he doesnt look though. Even though I have caught him many times. It's just breaking my heart. I feel selfish that I want to be looked at the way he sneaks away to look at others. I hate this feeling of jealousy and self consciousness.

Update: thank you for all your answers. I was feeling crazy and this made me feel so much better. I found out he looks at these models alllll the time. Like 20 minutes in the bathroom every morning and then come get frisky with me.. I am trying to be understanding that he has his own wants and needs, but he lied to me for so long about it and everyday...
