What exactly does "too intense" mean, exactly?

[John Elessar]

[Put this here because it is tangential to the often-dramatic relationships which often characterize SM/TS/etc. connections.]

I guess I personally thrive on the stuff-to me, someone saying something is too intense is like saying that ice cream is too delicious, so I won't eat it (diet issues aside), or that the sunset is too beautiful so I won't look at it. Why do people then run from or avoid intense relationships? Isn't that what life is ultimately all about? Wouldn't your curiosity outweight your fear in this case, wondering just how far the envelope can be pushed? Or am I being too naive about something that is escaping me here and which seems obvious to everyone else in modern society? Yes, in case you are wondering, I've personally gotten that line from some of the women I've dated...
