About licking and "sweetie" thing. Many people don't realise it's necessary to hold DISTANCE to other people. That's how you show them your respect of their personal space.
That might scale... for example, if somebody /lick me in
WoW and I have no real IC relationships with that character - IC Gharb would want to kill that person, OOC i'd feel very odd, because for ghods sake - your not my beloved to /lick me when you want to. In real life that's very important too... if I make a trip in transport and some careless man wouldn't notice me and would occasionally hit me or sleep on my shoulder - he might get a punch in his face. Simply because he means nothing to me and i want it to keep that way - there's something
private you don't want unknown people to even look at. It has to be deserved.
Even in your private life with your lovers/friends/relatives - you all want to have something private that nobody should mock or come close to, unless you give your permission. That's natural feeling in my opinion. Though of course maybe it's just me who feels like a predator guarding his own territory.
