Would You Get Upset If Your Boyfriend....?

Follows underwear models on twitter? Let me just say that the last time we were at Victoria's Secret, he pointed out one of the pictures and said, "Oh! That's___. I follow her on twitter." I didn't get mad but I didn't feel great and I thought it was insensitive. Then later I found porn AND underwear model pics on his computer (by accident, I wasn't snooping) and he didn't like that I was upset, but he deleted them. He said the pics were from before we got together and he forgot about them. He also says that those are only pictures, and I'm the real thing and that's what's important.

Anyway, I just checked twitter and he follows several lingerie models. He seems to follow them on all social media sites, like facebook, Instagram, and Twitter. (on Instagram he often likes other women's photos and it appears on my home screen) It just really bothers me. I'm not angry per say, but it makes me feel bad. Is this acceptable? What should I do??
