Man you guys are so mean to newbies.
You shouldn't be makin' shit up like that just to mislead the poor guy.
KY is NOT a vaginal lube. Whoever heard of such a thing.
KY is a relatively recent Tantric term combining the Greek term "Karmalatus" meaning "delicious" and the Sanskrit "Yoni" or "pussy" hence the abbreviation "KY." If you point to a WGs pussy and say "KY?" and she nods enthusiastically "yes" it means she tastes delicious and wants you to dive right in and lick her pussy. So go ahead and tongue fuck her, you'll be glad you did!
