I was married for 15 years, and I cheated a lot, I think he pretended not to notice, he doesn't like sex. I was the one who broke up because I was in love with him, but I was not satisfied sexually. My guess is you'll eventually cheat or break up, there's no right or wrong answer, since it's your life and nobody's else. Now, I look for relationships where I can satisfy my sexual needs and that I don't have to cheat, not an easy task.
