My SO works in an environment where his coworkers constantly exchange messages with pics of boobs, dicks (really small ones and really big ones), and gross pics like a dude Adult wants sex tonight IA Ely 52227 with a donut (don't ask). Most of the time, SO shows them to me and we have a laugh, or he laughs at my reaction. I personally don't have a problem with porn, so I don't a problem with guys checking out a woman's chest or other body parts because it is so one-dimensional. I wouldn't make a big deal out of it, unless he knows you're adamantly against porn, then I would ask him to be a more sensitive to your beliefs.
