Definitions

Female: anything with a vagina.
Woman: a female who engages in sexual activity when the mood is right, is concerned with mutual pleasure for her and her partner, and has complete discretion over who she engages in sexual activity with.
Slut: a female who engages in sexual activity that is most often initiated by her, more frequently than what is considered “average”, who is primarily concerned with her pleasure, and who has a broad range of personal criteria concerning who she choses to engage in sexual activity with.
Whore: a female who engages in sexual activity that is most often initiated by someone else, usually more frequently than what is considered “average”, but may also be denied sexual activity for a period of time as either training or punishment, who is most concerned with the pleasure of her primary partner, who is usually chosen by her, and for any other partners chosen for her by her primary.
Slave: a female who engages in sexual activity that is always initiated by her Master, as frequently or infrequently as her Master determines, who is not permitted to seek her own pleasure, who has no say over who she is used by and in what manner, and for whom sexual activity may be broadly defined to include traditionally non-sexual practices (e.g. torture, beatings, etc.)
Remember, these are definitions and do not necessarily encompass the emotional aspects that all human interactions include.  I only say that because I’m talking about my female counterparts, who I love and respect for the choices they make with their lives, and I don’t want them to think that I believe these definitions are all there is to it.
