True story: It's possible to give yourself a hickey at the back of your throat if you suck too hard. Not, you know, that I know from personal experience or anything. *koff*

I'm one of those people who think come tastes foul. Precome isn't as bad, if only because there's not very much of it (with most guys) and it's easily diluted by saliva, but the flavor is essentially the same. Salty and bitter, with this almost metallic-y aftertaste that lingers in the back of the throat and makes me gag. And while diet, etc., make minor changes in the taste, that aftertaste is always there, in my experience.

Further in the TMI vein, I've never really gotten what people are on about when it comes to the whole "cover your teeth with your lips" thing. I've never had a guy complain about my teeth, and I don't think I've ever (accidentally, at least *koff*) scraped anyone with them. And some of the penises I've encountered have been of the jawbreaker variety, so it's not even just that I have a big mouth and have only blown guys with little dicks. *g*
