Q&A Should I Believe This?

Dear Rick, Can this statement be true. "I have never thought of them while having sex with you"? I was the one that discovered my H's affair, D-day was 2/3/16. Later I discovered pictures of his AP/coworker on his phone, then again 2 more on our computer, and one of a hostess at a restaurant we eat at. My H took all of these "without then knowing" and they all are full boby shots (showing their great figures). In March he told me of another family friend/school employee who he has /had feelings, future desires /plans about. Found photos of her as well.As far back in 2012 on our daughters school camping trip/ they were both chaperones along with other parents. Also found 5 R &X rated trashy/porn movies on the computer which he said ,"when do I have time to watch movies". Should I believe him? He hasn't had sex with any of them. He told me.
