<human>: I (f/26) found dick pics in my boyfriends (m/27) phone and I fear he may be sharing them with someone else.  Does that mean he's cheating? 

He's not sending them to me so I know they aren't for me. In the past, I've found a couple of photos that he saves from porn websites on his phone as I found again recently. I'm not sure if these are also from online or if they're from a girl he's exchanging photos with. 

I'm almost 100% sure he's not actually having sex with anyone else since we spend most of our time together and he tells me his whereabouts otherwise. So I'm wondering if he does this for fun when I'm not around since I have a more hectic work schedule than him and if it's his way to get the release without having sex with someone? Is this considered cheating?

Provide a brief overview of the text.
