A person, in essense is someone who is master of his or her sexual appetite not its slave?​

Chaste.

Explanation:

Behavior modification is a therapeutic process that is focused on changing any undesirable negative behavior in an individual through the use of positive or negative consequence and biofeedback.

Behavior modification is typically based on operant conditioning principles, through negative or positive reinforcement, undesirable behaviors developed by an individual are mainly replaced with more desirable ones.

Behavior modification can also be used to correct human behaviors or disorders such as enuresis (bed-wetting), Obsessive-Compulsive Disorder (OCD), generalized anxiety disorder, Attention-Deficit/Hyperactivity Disorder (ADHD), phobias, etc.

Chastity can be defined as an act or quality possessed by an individual through which he or she is able to abstain from any form of sexual activities that are typically considered to be immoral. Thus, a chaste person refers to an individual who doesn't have any sexual experience or indulge in any sex-linked (sex-related) activities.

This ultimately implies that, a chaste person, in essense is someone who is master of his or her sexual appetite not its slave i.e being able to control and put in check his or her sexual urge.
