Instagram “models”

So my bf of 2 years has had this thing lately where he follows Instagram models on Instagram.. and the thing is they are all topless models and I feel like the majority of girls he follows are all these kinds of models. We’ve had trust issues in the past and it’s something we are still working on. However, I just feel like my womanhood is disrespected even though non of these “models” are realistic threats. Any thoughts or advice?
