Found this little list on the web a while ago and I agree with those statements for the most part. I took the liberty of deleting the really silly bits (saving trees by not using paper tissues) but there are still some interesting points here I’d like to share.

Why Swallow?
1) It’s Tidy:
Spitting is, quite simply, messy. Having a paper towel at the ready
can help, but even then, you have a cum-soaked towel to dispose of.
Same is true if he comes somewhere other than inside your mouth,
there’s plenty of sticky jizm to wipe up. Just swallow and there’s
no muss or fuss.

2) It Lets the Man Relax:
If a man has to worry about coming, feeling that it is an imposition
on the woman or the cause of unpleasantness, it creates tension
while receiving the blowjob. He cannot fully relax, and cannot fully
enjoy his climax. A woman who swallows both puts her partner at
ease. Also, she can continue sucking through the orgasm, “sucking
him dry”, which men find both physically and emotionally satisfying.

3) The Symbolism of Swallowing:
In Western culture, swallowing has deep symbolic significance. The
act of swallowing signals acceptance, blessing, and complete
transformation. Imagine spitting out champagne after a toast or
spitting out the wafer during communion. The insult and sacrilege
would be overwhelming. In the same way, spitting out cum is a
symbolic rejection to many men. By swallowing, a woman indicates complete acceptance. The semen becomes part of her, he becomes part of her.

4) It’s Polite:
To quote one woman: “What sort of message does that convey to
immediately run to the nearest sink to spit? I’m comfortable enough
to get down on my knees and wrap my lips around your cock, but not
comfortable enough to swallow the fruits of my labor? I know I’d be
offended if my boyfriend ran to the bathroom to gargle with
mouthwash after going down on me. So, sure I swallow. It’s almost
impolite not to.”
