Pornography? Yay or nay?

Ok ladies I need some help. Been in a relationship for a year and a half now and come to find out my boyfriend occasionally watches porn. I know it's a social norm but I was always raised to stay away from it. I don't enjoy it much anymore because I have my boyfriend now. No more lonely nights. Etc. I just feel like I'm not enough for him. He can't practice keeping his dick in his pants long enough for me to get home and spend time together. It's just so awkward and the sex has definitely changed. It used to be fun and erotic and now it's just kinda bleh. Could be that we have been together for so long or he is getting bored with me. What do you think? Am I overreacting? Please help!
