Sex with the ex

I am craving a penis, haven't had sex in months. I started talking to an ex from 3 years ago again, we agree that the relationship is never going to happen but he and I are great as friends. He is an amazing eater, I get multiple orgasms. Just thinking of him I am wet.

Does anyone by chance have gone back to an ex, no emotions just to get physically aroused? I trust him and feel comfortable. I don't love him but we mutual care for one another.
