I agree, there definitely is something very electric about it. It's very much about male bonding, being men together, and appreciating what makes us men. I have a jackoff bud and we do alot of this. We'll wrap hairy legs together and get shaft to shaft and just take our time stroking both, rubbing the heads together, and letting our balls massage together. Sometimes if we get worked up we'll just start grinding cock to cock and chest to chest. It always leads to explosive orgasms... and a really close friend. I highly recommend it.
