Consent to sexual activity:

Consensual sex is when both parties are of legal age, agree to engage in intercourse by choice, and have the freedom and capacity to make that choice. This means agreeing to sexual relations without fear, coercion, force or intimidation. Giving consent is active, not passive. It means freely choosing to say ‘yes’ and also being free to change your mind at any time…. If someone is not able to give consent to sex, regardless of their age, it is a crime to have a sexual relationship with them

同意性行為：

自願性行為是指雙方都達到法定年齡，同意透過選擇進行性交，並且有自由和能力做出選擇。 這意味著在沒有恐懼、脅迫、武力或恐嚇的情況下同意發生性關係。 給予同意是主動的，而不是被動的。 這意味著可以自由選擇說“是”，也可以隨時改變主意… 如果某人無法同意發生性行為，無論其年齡如何，與他們發生性關係都是犯罪行為

什麼是同意？

同意意味著您自願同意進行性活動。 如果某人有以下情況，則可能被視為無能力同意：

酗酒或吸毒

睡著或失去知覺

身體、精神或發展障礙，包括患有失智症的老人

低於該州的同意年齡

What Is Consent?

Consent means that you freely agree to engage in sexual activity. Someone may be considered incapable of consent if they’re:

Intoxicated on alcohol or drugs

Asleep or unconscious

Physically, mentally, or developmentally disabled, including a senior with dementia

Younger than the age of consent in that state

請注意：以上 與有沒有錢，有多少錢 完全不拉上關係。 在北美國家的法律上，錢不可能把任何犯罪行為 合法化。

若把錢與性行為拉上一個交易的關係的話、、、、

為什麼不能支付性費用？

Consensual sex is legal. But as soon as one party offers cash to another in exchange for sex and that money is voluntarily accepted, it’s considered prostitution, and that is illegal （In Many States but not all）.

雙方同意的性行為是合法的。 但一旦一方向另一方提供現金以換取性，並且這些錢被自願接受，就被視為賣淫，這是非法的 (在許多州 不是所有州)。
