<human>: Summarize the given text in a few sentences.

We have been dating for ten months almost. It's a semi long distance relationship and he lives about two hours away. We see each other on the weekends. We usually have a healthy sexual relationship. We are also toying with the idea of swinging, and have gone to a couple of swing parties. 

In the past month, the sex has slowed, which I wasn't too worried about. We have both had a lot going on. He pretty much always has a high sex drive. However, he has mentioned how he just hasn't been in the mood. A week ago, I attempted to wake him up with a blow job, and he said he was not even remotely in the mood. Since then, he has shown no interest. 

Today I used his iPad to look at houses and I opened his browser history to find one I had looked at earlier and found hundreds of porn searches over the past few weeks. Some were innocent and just normal guy stuff, but he has also been searching craigslist for women looking for sex.. Usually married women and men where the man wants to watch his wife with another man. Even on days when he was showing no interest in me, he was looking at this stuff. So what gives? Am I just being distrustful or is this weird? What do?
