Is my boyfriend lusty or is this normal male behaviour?

So it's been more than 2 years and it's my first relationship, earlier he was all over me but when the honeymoon phase is over , I feel. like this relationship is getting boring lately , even his texts are short now and replies when he likes to I guess... i discovered his insta watch history and i noticed that he often watches random influencer girls and models, there are always girls on his way history... i don't know is it something okay? or red flag? he never reaches out or anything to those girls but he often searches for this 7-8 names often and also the random girls...

Should I be okay with it? or is he a jerk?

Is my boyfriend lusty or is this normal male behaviour?
