Is no contact my only option if he won't chase me?

I'm open to any suggestions. I have an unhealthy crush that is bordering dysfunctional. I'm interested in a man that sleeps around, some may even say it's excessive, and he isn't secretive about it but it doesn't deter my feelings. We've become pretty tight friends but we have obvious chemistry. I think maybe we're both shy? But with women he is never hard to get. Far from it. Maybe I'm portraying my interest to him wrong. Possibly he flirts with me because he's just slept with everyone else but it feels genuine, when sometimes he stutters and he can rarely keep eye contact when we're close. It's adorable but I need more. I don't think to tell him is wise. I want to let him pursue me right?
