Samoa
It is an offence to have sexual intercourse with a girl under the age of 16: sections 51 and 53 of Samoa's crime ordinance. If the girl consented and is aged 12 or more, it is a defence if the defendant was younger than the girl, or if he was under 21 and "had reasonable cause to believe, and did believe" that the girl was aged 16 or older. These defenses do not apply if consent was obtained fraudulently. There is no minimum age of consent for boys, although sodomy is illegal at any age (section 58E) and it is illegal for men aged 21 or more to commit indecent acts on boys under the age of 16 (section 58C). Similarly, it is illegal for women aged 21 or more to commit indecent acts on girls under the age of 16 (section 58B).
