pretty upset..

Kate
So. My fiancé and I don't have sex too often (once every 4-6 weeks). I'm a more sexual person than he is. Which is more than fine. I feel like I've tried so many things to make him feel comfortable (I feel it's insecurity) with me and everything. I've even compromised and had less sex because that's what he wanted (don't let stereotypes fool you) 
But tonight i decided I'd have a look at his photos on his phone because a couple of times before he had naked girls saved there. I haven't looked at his phone in about a year. But tonight I did. And discovered that he has saved snapchat profiles that are porn!!!! WHAT THE FUCK!!! 
If we had sex more often I'd be fine about this, I like to watch porn sometimes too but only because we don't have sex as often as I want. And he's been watching porn instead of having sex with me?!!!! 
I have a right to feel upset, right??? Or not? Do I confront him about this?? If so, how? So he doesn't think I'm checking up on him.? I legit haven't looked at his phone in ages!
