F%ck Buddy Etiquette?

So when it comes to having a f%ck buddy is there a particular way we have to do certain things? I mean, on arrival to the 'meeting of choice' whether it be a cheap pop-in hotel, parking bay near a park, sneaking in through windows while their parents are home etc... Do you hug, kiss or awkwardly stand there and wave hello?
Most people will experience having a bed buddy and some of the reasons for that may involve;

• Just got out of a serious relationship, doesn't want to commit to anyone.
• Too busy for a relationship, (for whatever reason).
• Revenge fucking.
• Accidental sex, (drunk sex).
• Unsatisfied in their current relationship.
• Friendly romping.

 When you're lying down (or what ever position you're in) mid penetration,  are you being held in an embrace, a choke hold or not at all? Is it wrong to assume that you should be treated in a certain way? There are so many questions that need to be asked, however are hardly ever spoken aloud, why? Because once you ask these questions, you become the relationship initiator and no one likes those. Can you imagine after you're both putting your clothes back on and wiping remaining love-juices off of yourself, you go to say goodbye, don't know what to do, panic and then ask something stupid like "so do we kiss goodbye or something?"

Having a fuck buddy is supposed to be fun, when feelings get involved when there's already an arrangement, things can end up quite messy. It really makes you think, "since when did sex become so damn complicated?"
