Spit or Swallow

Somebody asked me that today, do I spit or swallow? According to my friend, not many women swallow. I've never really had a problem with swallowing... does that make me a slag?
I haven't really slept with that many people.. in fact, my illicit affair is the sixth person I've ever slept with. And I'm in my mid-twenties (nearer 30 than 20) and I can name every person who I've seen naked and who has seen me naked. Every person who has gone down on me and who I've gone down on.
I know that you should really stay away from dairy products if you want your lover to swallow...
