<human>: Condense the text into a few key points

My boyfriend used to very much be into porn growing up, especially in his late teens. He would watch it allllll day. He was also not very "nice" to women and seemed to have a one-track mind if you know what I mean. But with me, he has always been very nice and respectful. We're good at solving problems and he values my opinion. We are two peas in a pod in terms of personality, ways of thinking, and interacting with each other.

So anyway, he claims to not watch porn, and I'm not sure if I believe it. It's not that he's ever given me a reason to think he's a real liar, of course there were a couple little white lies but that's honestly it. This, combined with his history, what the internet has told me, and the fact that we are also long-distance... I don't know. I'm thinking that in-between visits maybe he watches it. It's just shoved down my throat in the media, reddit, etc that guys watch porn and lie about it. Sometimes we like to talk to each other about when we have self-sexy time (which he does a lot, which is another thing) and what we thought about, and he always has something prepared to say. He says that he thinks about when we do it in person and always remembers detailed events. But that could just be him preparing in advance for when I ask... I don't know.

So why is this an issue? It's not really. Porn isn't an issue to me. But I'm worried for the fact that he might be lying to me or that I'm not providing enough for him. Every couple months I'll bring it up and tell him that I'm fine with porn and he can watch it if he wants to, I'd just like to know. Regardless, he always says he doesn't.
<bot>: I don't believe my boyfriend when he says he doesn't watch porn. I've read too many things to believe otherwise. I'm just concerned that he may be lying to me. What can I do?
