found porn on husband's phone

I've always been against it when we are alone and he knows this, so finding it really upset me. I'm sure being pregnant doesn't help my self esteem either (33 weeks today). I haven't been in the mood for a long time and I feel bad, but that's just how my body is right now. but seeing younger girls and obviously not pregnant on his phone bothers me. am I over reacting? yes we have access to each other's phones. now I'm feeling self conscious and weird about even trying to do anything intimate with him after finding this. I'm pretty sure he wasn't expecting me to find it in his search history because when i confronted him, he had no words. how would you feel?
