Why does my boyfriend still want to have sex with me, and still want to be with me, even when he looks at naked pictures of his friends that are girls. And he's even sent pictures of his penis back too. I just don't understand. They're, in my opinion, not even pretty. I've confronted him before, and he just said they sent him pics and he didn't even want them. But he did it again with someone else and tried hiding it from me when he did it, but I saw what he was doing. I just don't understand. He denies, denies, denies, but I know the truth. And he tried talking to his ex, I confronted him about that he of course denies that, blows up at me, then stops talking to her. I feel like I'm going crazy. Like I said I just don't understand.
