I'm going to take the node title in the most depraved frame of mind possible: Blow Jobs. How else would you expect me to take it?

I personally think that ccunning has a good portion of it right. Now, never having been the recipient of one of these, I can't attest to the pleasure factor that LordOmar points out, but I do think that, honestly, if after the deed my significant other raced to a trash bin and hocked it out, I would be hurt. I don't know why, but I would be hurt. Sort of like when someone tears up and throws away a birthday card right after they read it because "it served it's purpose, didn't it?"

And as for the issue of some women not understanding why it could be such a big deal, think about this: What if the tables were turned a bit? Ladies, what would happen if your lover, after they had made you cum rivers like no other, quickly ran off to the bathroom and gargled inscesantly with Scope? Most women would feel hurt, I guarantee it.
