the dynamics of the Friends With Benefits "relationship"...

There are 3 main components of the "FWB" interpersonal relationship---
1. It must always be about having FUN.
2. The sex must be GOOD.
3. There can be absolutely NO COMMITMENT.

This type of relationship, actually, now that I think about it I really don't think it can be called a relationship... how about arrangement? Anyway, this arrangement between two people is TEMPORARY, usually SHORTLIVED and DEVOID of any kind of involvement of FEELINGS.

If ANY of the 3 components are NOT adhered to, the arrangement will fall apart faster than you can text "what r u up 2? want 2 come over?"

Other factors involved in the collapse of the FWB are the possibilities of meeting someone else you'd rather have as your fuck buddy, the person would of course have to be; more fun, better in bed, totally non commital and, in this shallow world we live in, hotter. which could mean; younger, fitter, more educated, wealthier, better structure, etcetera than the person you are currently hookin' up with.

If you plan on giving the FWB arrangement a shot, please, make sure BOTH PARTIES are aware of the status. NEVER assume they know. This will ensure nobody gets hurt.

Remember; no future... no past... just now.
