Why is my husband looking up woman on Facebook?

What does it mean if your husband is looking up a bunch of woman on Facebook? I'm ignoring that fact that i saw it briefly while I walked up to him from behind the couch to give him somthing... he turned off his phone pretty quick, I don't need an unnecessary fight. So im not bringing it up... everything is great. Our sexlife is great... But I am hurt by it.
