what do i do about this guy I'm talking to?

This is very personal to me so please people be considerate. I am talking to this guy via the phone met on yahoo, since '07, never wanted anything more than a male friendship from him. He decided to drop the L bomb word and that changed everything, now we talk everyday and he genuinely shows that he cares for me. Problem is this boy always have pics of naked women doing sexual things on his profile pic. Say were playing a game on some website and these pics are up for all to see. I told him to take them down it's offensive not only to me (but mainly me),but little kids are on this gaming website what if they see it. He took it down but then i found out he had several more. He claims he doesn't remember the website of where he got the pics ,yeah right. So what should i do ,i feel a little insecure i guess i never felt insecure before with someone but this is a little different. I haven't met him yet the long distance thing is killing me, should i just call it quits or get over it because there just pics?
