Having a "friend-with-benefits" arrangement is quite possibly the BEST situation ever.  But if you aren't careful . . . it can turn into a complete disaster. 

With that in mind, here are some rules for the CORRECT way to have a friend-with-benefits relationship.

#1.)  Never use pronouns like "we" or "us" when you're talking about your friend with benefits.  There is NO "we" or "us" . . . and that's the beauty of the situation.  Also, never talk about "the future" . . . or make plans that are more than an hour or two away.

#2.)  Meals are things you have with friends WITHOUT benefits . . . and people you're dating.  They are NOT things you have with friends with benefits.  I repeat:  Friends with benefits DO NOT have meals together. 

#3.)  Conversations need to be kept light . . . and centered around relations.  The minute you start talking about your family, your life or anything of real substance . . . you've violated the unofficial friends-with-benefits agreement.

#4.)  Keep your friend with benefits as far away from your REAL friends as possible.  I can't stress this one enough.  Under no circumstances should you introduce your friend with benefits to your family or friends.
