Boyfriend watches porn with friend

My boyfriend watches more porn than I would like. I'm okay with him watching some and can understand that for an introvert, sometimes it is easier for him. It does bother me that we don't have sex very often and he is looking at other women. I have expressed this to him and he says that he desires me and will make an effort to show me. The last time we had this conversation was 8 weeks ago. The last time we had sex was 7 weeks ago. So really, nothing has changed. Today he was hanging with his friend in the other room and I came in to see if they wanted something to eat and they've got porn projected onto the wall. I know it was him to put it on because it was large breasted women, his favorite. They acted like it wasn't weird at all and I'm sure it wasn't the first time. Is this normal?
