Unsure, unsexy, and insecure

So my boyfriend of 4 years it's wicked awesome funny sweet nice and an amazing lover he always makes me feel good about myself, but I recently found he's watching/has been watching porn, like a lot of porn. Almost ever day and he has a favorites list. It's been making me feel really shitty about myself and if there's anyone else who's been through feeling really down on yourself, I just don't feel good enough or can compete with those girls. It makes me feel like he doesn't want me. Thanks for listening
