[42m and his 37m partner] With online interactions, is there a strategy that suits you in this situation? We've been together for seven years, but I'm starting to worry.

I’m a 42-year-old female and my partner is 37. We’ve been together for seven years and have previously talked about pornography, where I expressed my concerns, and he assured me he would stop using it. While I know he uses it less frequently now, I recently brought up the new Instagram feature that allows users to see the reels that others like. Today, I noticed a suggested account that belongs to him—it's a public account with no posts yet. How should I address my concerns about this? Should I follow him first or ask him about it directly? His sister and mutual friends also follow this new account. In short, I’m a 42-year-old woman worried about my 37-year-old partner’s online activity.
