Rape required vaginal penetration of a woman. Anal penetration could not constitute rape. It shall not be necessary to prove the completion of the intercourse by the emission of seed. That the intercourse shall be deemed complete upon proof of penetration only. See Gaston at 167.
Bestiality requires vaginal or anal intercourse with an animal or by an animal.
36 Criminal Appeal Reports 125. The 1976 Act defined the offence of rape. If a woman has a natural vagina which is anatomically irregular as a result of a birth defect, an operation or an accident, it would in my judgment be rape to penetrate it. I have been referred to no authority directly on point. In that case the respondent to a petition for a decree of nullity, was born a biological male who, like the complainant, had undergone gender reassignment surgery involving the construction of an artificial vagina.
