The white silk slave is not necessarily virgin, merely reserved for her Master/Mistress's sole use. They are generally permitted to serve drinks and food and conversation but sexual use is forbidden and corporal punishment is at the hands of the owners. Masters and Mistress's insulted, may embarrass, confine or display the slave, but may not strike in any way nor permit another to do so. They do not use the term "slave heat" except in serves to their Owners. There is some controversy in using this term as many Goreans feel only a "true virgin" should be white silk, this view varies depending on the region of Gor.

The mark of a pleasure slave...may generally be used by any who desire her usage but may be reserved for the sole use of the owner. A pleasure slave is considered to be well trained to please in all ways sexual, service wise and in dancing, and are closest to the houris of the Arabian harem. True "passion slaves" are bred for that purpose specifically, one that has been bred for a particular trait, such as beauty or slave heat or the shape of her lips and no barbarian can attain that rank. They usually have a club foot from inbreeding etc.
