Been over a year

My boyfriend and I have been together a couple years and he has lost interest in sex with me (he does watch porn). We had a raging sex life when we started out but it has dissolved to non existent. Most parts of our relationship are good, he's a good person, but I'm wondering what the next step for me is. It feels shallow to want someone more compatible sexually, with no guarantee I'll find that. Maybe that's just the fear talking.
