How Many Edges Before It’s Too Much?

I love the rush of being edged over and over, but I swear there’s a fine line between pleasure and absolute torture. The longest I’ve gone was probably an hour of nonstop edging, and by the end, I could barely think straight. One thing that helped me last longer was focusing on slow, steady breathing—it keeps the body from completely losing control too soon. But at some point, the frustration gets so intense it’s almost painful. Is there such a thing as too many edges, or does the limit just depend on how much you can handle?
