A sexual inhibition is a conscious or subconscious constraint or curtailment by a person of behavior relating to specific sexual matters or practices, a discussion of sexual matters or viewing certain sexual material. To some extent such inhibitions may arise from cultural and social influences and conditioning, as well as from personal factors, including sexual orientation. In most partner relationships, the level of inhibition tends to decrease the higher the level of trust that develops between the partners. Such inhibitions also tend to decrease with improvements in a person's confidence in their sexuality. A person may take a drug, such as alcohol, to reduce their level of inhibition.
