<human>: Can you summarize the given text in a few sentences?

Edit: [34/f]. Story: He's looked up **many** women, all cute, almost exclusively in their early 20s. He usually goes through all their photos once, some he returns to a couple of times a month. If he can't find her right away, he may spend an hour or more figuring out her last name, looking through employees at places she works, going through friend lists, looking for events she might have attended...then he'll flip through her photos once and that's it. Perhaps a celibate means of conquest? Once he finds her & ogles, the urge is satisfied?

Though I find it a little creepy, I don't mind too much that he likes looking at pretty girls. FWIW, I'm pretty sure he's just looking, not trying to hookup. He is happy in our relationship of 4 years, and I cannot imagine him going after someone 13+ years his junior. If he does, he's an idiot. I'm mostly wondering, is this common?

New account because he knows my UN. I was looking for a site I had used on his computer, saw all this in his history. I know I can't justify my snooping. Scold if you like, but please answer the question :)
<bot>: Boyfriend of 4 years appears to Facebook stalk every attractive woman he meets. Every. single. one. Most of them he flips through photos once, some he returns to repeatedly. Is this normal?
