For the guys only??

A good piece of *** is a girl that likes to have sex as much as the man does, she is aggressive, makes it fun, and says no to very little. She is not worried about looking fat or making a mess, she wants it to last all night!

this is a hard one to write because this is guy's talk but you want to hear it. A good one that is tight or still in good shape and well taken care and one that enjoy what is going on and like as much. A bad one is not so pretty and just lay there and most likley you wouldn't want to be seen in public with her kind of like a mopad they are fun to ride but you wouldn't want to be seen in public on it. They all have to smell good if you know what I mean.

Most of all at least for me all have to have a good attude.

but I haven't don't this to manytime's Good question

Besides the obvious quality of sex appeal (curvy figure on an athletic frame, at the least), a good one is one that has a carefree attitude and is up for anything.

A bad one is one that gives the impression that she would judge you for what you say or do.

I've always heard guys say even a bad one, is a good one...apparently for some, there is no such thing as a bad one...

Well if your talking sexually a good piece of a$$ would be someone who doesnt lie there like a sack of potatoes.

A bad one doesn't know what a guy needs. A good one does.

the worst piece you ever get is marvelous

good question

wish i knew so i could fix it
