First of all, are these just pics from some porn site on his phone? Or are they pictures from women that he's actually talking to? That would make a huge difference. Some porn site pics, eh, whatever. But if he's actually talking to women and they're sending him naked pictures, then that's a big no-no. As far as the porn thing goes, this is one of those times when you have to pick your battles. A lot of men look at porn. That doesn't necessarily mean that you have to accept it if it *really* bothers you, however, it does mean that you'll probably have a hard time finding a guy who doesn't occasionally look at it. If it's actually getting in the way of your relationship, or if he can't perform without porn, or watches it obsessively, then that's definitely a problem that should be addressed. But, if he's just looking at it every now and then, you have to ask yourself if that's really worth starting a fight over.
