What is a necessary element for the crime of sexual conduct for a fee?

The necessary element for the crime of sexual conduct for a fee is that there must be a transaction involving sexual conduct, specifically that there is an agreement to engage in sexual conduct for payment. This means that the individual involved must actually participate in, offer, or agree to sexual conduct in exchange for monetary compensation.

This element is fundamental because it establishes the illegal nature of the act based on the exchange of sex for payment, which is a defining characteristic of the offense. Without this component, the crime would not fulfill the criteria set forth under the relevant statutes that regulate sexual conduct and prostitution offenses.

Other options, while potentially relevant in the context of a broader discussion around sexual conduct and legality, do not serve as necessary elements of the crime itself. For instance, the requirement for a third party's involvement is not essential to establish the commission of the crime, nor is the need for the customer to be aware of the law or the occurrence of sex during the engagement. Each of these aspects could pertain to various legal arguments or defenses but do not constitute the core element required to define the criminal act of engaging in sexual conduct for a fee.
