Sometimes there is a desire by the "poly"to keep his "PolyFuckery" to him/herself simply because the partner,he/she has is Not poly...Its a simple device thats employed to protect the feelings of the person who is being betrayed in their eyes...And yes...It is a betrayal...And yes...Ive been guilty of it...Who hasnt been guilty?....Betrayal itself comes in many forms,the heavy flirting,the sexual cyber promises,the insinuations,the women having their breasts stroked,the men having their cocks stroked through their trousers,the revenge one night stands ...Or isnt all that "Polyfuckingaround?"......Right... I forgot..Thats innocent play...Im not adept enough to answer any further,so will let others with a better grasp of grammar try to continue this debate..
