Does your boyfriend know it bothers you that he does this?

Have you talked about why he looks at porn?

Why does it bother you?

I think that's probably more of what you were looking for....

Even the most sexually satisfied man will look at it...they just do...it satisfies their visual stimulation center....it's just how they are...

I think by telling him it bothers you you can get it out in the open, but it won't make him stop, it will just make sure he does it when he can't get caught.
