Romeo and Juliet laws

 

性交同意年齢は『性行為がどのような行為かを理解し、自分が性行為をしたいかしたくないかを判断できる年齢』ではありません。その年齢未満であれば、刑法で強姦ときめうちすることです。刑法だけでなく、未成年であれば、児童福祉法や淫行条例で処罰される可能性があります。 https://t.co/CWIQGtLGvK

性交同意年齢とは？

ということで、Statutory rape

From Wikipedia

その趣旨は、

By making it illegal for an adult to have sex with a minor, statutory rape laws aim to give the minor some protection against adults in a position of power over the youth.

 Because forced sexual intercourse with a minor is considered a particularly heinous form of rape, these laws relieve the prosecution of the burden to prove lack of consent. This makes conviction more frequent in cases involving minors.その趣旨は、

大人からの性的搾取されるのを防ぎ、また犯罪の悪性に鑑みて、裁判での立証の負担を軽くすることにある、と言われる。

Statutory rape laws are based on the premise that an individual is legally incapable of consenting to sexual intercourse until that person reaches a certain age. The law mandates that even if he or she willingly engages in sexual intercourse, the sex is not consensual　Critics argue that an age limit cannot be used to determine the ability to consent to sex, since a young teenager might possess enough social sense to make informed and mature decisions about sex, while some adults might never develop the ability to make mature choices about sex, as even many mentally healthy individuals remain naive and easily manipulated throughout their lives.[13]

仮に、 「性行為がどのような行為かを理解し、自分が性行為をしたいかしたくないかを判断できて」なおかつ、やりたいからやったのであっても、この年令以下だと、「不同意」であったとみなされるわけだね。

　ただ、ウィキを下まで読んでいくと、buveryさんのような懸念がある場合は、国によっては、

Romeo and Juliet laws

ロメオとジュリエット法で対処している、と。

 In Canada, the age of consent is 16, but there are two close-in-age exemptions: sex with minors aged 14–15 is permitted if the partner is less than five years older, and sex with minors aged 12–13 is permitted if the partner is less than two years older.[45] Other countries state that the sexual conduct with the minor is not to be punished if the partners are of a similar age and development: for instance, the age of consent in Finland is 16, but the law states that the act will not be punished if "there is no great difference in the ages or the mental and physical maturity of the persons involved

例えば、カナダでは、同意年齢は１６歳だが、１４，５歳との性行為は、相方との年の差が５歳以内なら許され、１２－３歳の場合、年の差２歳以下なら許される、などの規定がある、と。
