Jealousy/insecurity about husband looking at other women on social media

My husband 28m, and myself 27f have been together for 10 years. The last couple years of our relationship have been rocky to say the least. We weren’t communicating to one another, we kind of coexisted in the same house and our sex life (my fault) was essentially non existent. A few weeks ago we had a massive heart to heart, a deep conversations, fully communicated our issues to one another and our relationship has improved tremendously including our sex life.

Before our heart to heart, I didn’t care if he watched porn at looked at other women at all cuz I wasn’t invested in the relationship. Now we have rekindled I still don’t mind and he knows that. I’m completely aware that he may see a hot girl on social media and want to have a quick look, I totally understand if I’m not in the mood or if he wants a quick release he might want to watch porn. That’s totally fine. What I’m really struggling with is the extent to which iv realised he does it. Not the porn so much but the women mainly on Instagram/Twitter. I mean both socials are riddled with very attractive half naked women and like I said if he happens to come across a picture here and there I find no harm in him looking. It’s the fact that he actively looks for the pictures and whenever there is a picture he looks on it, then goes to the girls profile and scrolls through several more pics. This is taken further than celebrities on Instagram models/influencers and he will look at people he may know/acquaintances ect (I know this because I was looking through search history on our shared computer-not snooping I was looking for a specific coffee table I had seen a few days before)

Anyways, I want to know if this is normal? If I’m overreacting? If it’s solely me needing to work on my insecurities? If not how do I approach him about it without sounding jealous and insecure??
