Men looking at women?

Can you men really only love and want your girlfriend or wife but still look at every girl on social media that’s basically naked?

My boyfriend looks at girls all the time on snap and TikTok but says he doesn’t want them and says he doesn’t find them more attractive and that he loves me. But can men really only want there girlfriend while still looking at all the women in the world? Should I be worried or should I just try and let it go.
