A male slave kept by a woman owner for bedroom duties is a "silk slave" (while most male slaves on Gor are used for unskilled hard labor in work gangs). When a free woman makes use of a kajirus sexually, he is often chained so that he is unable to hold her in his arms — since allowing this would be considered to add a note of male domination to the lovemaking. Some free women carefully avoid kissing a kajirus when making sexual use of him, since they would consider it degrading to soil their lips by touching them to the body of a mere slave. Note that only a small minority of rich free women on Gor own silk slaves and (in contrast to the usual situation with free men and kajirae) it is often not very easy or convenient for a free woman to obtain the sexual use of a kajirus whom she does not personally own (in the city of Ar, the largest city of known Gor, it is strictly forbidden by law).
