do I say something

So I happen to go onto my SO phone today and it had died so of course it opens up to what he was looking at last witch was porn okay no problem with him looking at it but he was looking at it before he came in our room for booty so do I not turn him on anymore?? I just feel hurt because he was looking at skinnier girls before coming in to fuck me like wtf I already have body image problems specially now since I've had my daughter. Idk I'm just feel really low seeing that now. And he always wants me from behind now no other way. I just wanna cry. Do I say something to him or do I just keep it in and not let him know I seen it.
