Hey Mandy,
To answer your above question about tasting your own...
The problem guys have, is that the "urge" to try that is gone almost the instant we cum. Maybe thats why it is always better if the other guy comes first because you are all hot and horny still.
Of course, in todays "Safe Sex" society we aren't supposed to be spitting or swallowing. So unless you are a monogamous couple, the only safe spunk is your own I guess! LOL.
