Definition of rape: specified non consensual penetrative and contact acts rendered unlawful where consent is absent or vitiated. Rape is defined as specified forms of non-consensual sexual penetration or contact by a man against a woman, including penile penetration, insertion of objects or body parts, manipulation causing penetration, or oral application to genitals. The statute lists circumstances negating lawful consent-against her will; without consent; consent obtained by fear; mistaken belief about husband's identity; inability to understand due to unsoundness of mind, intoxication or stupefying substances; involvement of a woman under eighteen; and inability to communicate consent-and defines consent as an unequivocal voluntary agreement, while excluding medical procedures and intercourse with one's wife not under eighteen years.
