 //Aphrodisiacs,// powerful, addictive sexual enhancers that cause a mental and physical state not dissimilar to traditional hypersexuality. These drugs are based on female hormones, and may have long-term effects similar to female hormone reassignment treatment. They are strongly addictive, both physically and mentally, and the usual recommendation to slave owners is that slaves should be put on aphrodisiacs only for a brief time, or permanently. Aphrodisiac addiction can typically only be overcome by supporting a slave through withdrawal for a similar period to the amount of time she was on the drugs.
 Aphrodisiacs can also be administered in //extreme doses.// This is medically dangerous, but is sometimes used by unscrupulous slave owners. Slaves so dosed will feel an extreme need for sex regardless of their emotional state; for example, rebellious, virgin slaves on extreme aphrodisiac doses will typically enjoy having their virginity sold.
 
+//Anaphrodisiacs// are in many ways the opposite of aphrodisiacs, in that they limit the slave's libido. However, their method of action is generally slower, gentler and less damaging to the body's chemistry. They atill allow for a healthy appetite.
