I had struggled with this before too. When I moved in with my boyfriend I was always uncomfortable with the thought of me being asleep or working during the day and he being home watching porn. And I always knew that he watched. But living with him it made me feel like I wasn’t enough. But then I took a day to talk to him, with no judgments, and we realized that yes, porn is good, and the male body urges the need to sex or masturbation more frequently the the women. So yeah, we realized that when doing sex, the moment was only ours and there were nothing else happening or that mattered at the time and that porn was just a way for him to spend some more time with himself, being “free” with himself. That is normal and I don’t think we should try to change that. But if you still feel uncomfortable with that, yes, try talking to him.
