<human>: When my boyfriend and I decided to be exclusive, he asked me if I wanted him to unfollow these supermodels he checks out on instagram.  I don't really feel jealous about him looking at other women, as I feel such impulses are natural, and he's been loving and devoted.  So I told him I didn't mind.  

That said, sometimes I wonder if and where I should draw a line.  The other day we were hanging out and looking at his instagram feed, and he started commenting on how "hot" they were, how nice their specific features were.  When he did that, I didn't feel threatened or jealous, as if he would leave me, but I did feel insecure--as if I don't measure up;  I'm cute and all, but I'm no supermodel.  I wonder if I should have said something, but I don't know if I'm overreacting.

Can you summarize the given text in a few sentences?
<bot>: How do you feel about your partner's using media (hard or soft porn, instagram, etc.) as outlets in a monogamous relationship?  Have you had to set boundaries, and if so where/how?
