<human>: Can you succinctly summarize the text in 1-3 sentences?

Hi all. I am using a throwaway. I am 29f and my boyfriend is 32m. We have been dating for a little over a year. 
He lent me his hard drive and of course I gone and did what I shouldn't have. I went snooping. 
In his Pictures folder in his hard drive I found a folder of many different random girls I am assuming he found on facebook. all of the girls were originally in bikinis but the bikinis have been airbrushed out and replaced with basically what should be under those clothes. 
I was a bit shocked because this guy is a complete gentleman, or so I have been led to believe. The creepiest part is I saw some pictures of his ex as well. I guess I would probably have been more accepting of this album if he was doing it to random girls but this was a girl he had a connection with, a girl he loved, a girl who he supposedly have respected and still should respect. 

I am equal parts disgusted and creeped out. 

So reddit, what the hell? Men, do you really do this? Could he be practicing his photoshop skills or something? Why use his ex's pics? 

Oh and I guess this should also be a commentary about not posting your bikini pics on facebook, girls. I am now very happy and proud that I am very careful with the pics that I post. 

How will I approach him about this? Should I even?
