[Hourglass]

Sort of mixed feelings on it, for me.

On one hand, I wouldn't expect someone else to do it if I weren't willing to do it myself (fair's fair, right?). But on the other hand, something I read several years ago stuck with me and I can't (mentally) seem to get around it:
"Semen tastes like egg white mixed with sea water."

That...doesn't sound pleasant.

So oddly for me it isn't the fact that it's something that springs from within a human body that puts me off...it's the possibility that it might taste "yucky".
