Kāmesu-Micchācāra
					
					kāmesu-micchācāra:lit.'wrong or evil conduct with regard to sensual things'; 'unlawful sexual intercourse' refers to adultery,and to intercourse with minors or other persons under guardianship.The abstaining from this unlawful act is one of the 5 moral rules (s.sikkhāpada) binding upon all Buddhists.Through any other sexual act one does not become guilty of the above transgression,which is considered a great crime.The monk,however,has to observe perfect chastity.
In many Suttas (e.g.A.X.,176) we find the following explanation:He avoids unlawful sexual intercourse,abstains from it.He has no intercourse with girls who are still under the protection of father or mother,brother,sister or relatives,nor with married women,nor female convicts,nor,lastly,with betrothed girls."
