My dear friends...it all boils down to mental perceptions. Ask a
vegetarian to imagine the taste of fried chicken and he'll probably
feel like puking! Actually, there are alot of girls in SG who like
SHARING the EXPERIENCE of having their bf cumming, be it whichever
part, when they're an intergal part of it, and not just the guy
having his way!
Incidentally, cum is made of a heck of alot of things, and yes, a
lot of amino acids or protein! As for what it tastes like -
organic!
