Is it wrong for my bf to like these pages on facebook? males please answer?

[Anpoweichapy]

I have gone back to my home town to see my family. While I have been gone, I see that my bf has added a few "porn" type pages to his facebook. I have no problem with him watching porn, but for some reason I feel a bit funny about him liking these amatuer pages (especially since I have been gone for a bit). I know that it is like porn, but I feel uncomfortable that the pics will show up on his newsfeed every day, and also that random girls that arent porn stars can post their pics for fb users to "like, share and comment". Am I being reasonable in the fact that I feel uncomfortable about this? Why is he liking these pages?.... He has not given me any reassurance as into why. Take note males, females appreciate reassurance!
