Need advice WWYD?

I've been dating this guy for about a year and a half. I have a house with my kids and he sees his kids on the weekends at his. It works. We like our space and see each other plenty. My issue is the sex. It isn't mind blowing bc he basically has Erectile dysfunction. He makes up for it in other ways, kind of. However, due to the stress of his work (or lack of) and life, we haven't been intimate in more than 3 months. I've tried talking to him about it but he just blames it on stress. I feel like a nag. But jeez.....I'm a woman who wants some intimacy. Would you stick it out or move on? As far as a serious relationship later with him, I could take it or leave it. But I do have feelings for him. 😞
