The actus reus or elements of the crime of prostitution under Texas law are a willful agreement to engage in a sexual act for money and the intention to commit the act of prostitution. This is part of why entrapment plays such a prominent role in so many prostitution cases throughout the country; it is relatively easy for a prostitute and their client to claim they were simply engaging in consensual sex, and the burden of proving the actus reus of prostitution rests on the prosecution.
