Friends with benefits, how much is to much?

My boyfriend broke up with me a while ago and I was completely devastated, but I'm moving on now but I don't want an actual relationship with anyone. I have a stead hook-up guy, not really a FWB cause we were never friends we just hooked-up one time and still do. But I also have a certain guy friend that I've always flirted with and our conversations can get rather dirty, anyway he thinks we should hook-up and I want to, but what about the other one? Can you cheat on a hook-up guy? Is it too much to have two hook-up guys?
