An adult massage or body rub is not automatically illegal, depending on what parts of the body are massaged.
Most local jurisdictions have regulations of massage, including requirements for the masseuse having a certain amount of training and having a license to practice massage, and rules about what areas of the body may be or cannot be massaged, and perhaps, even, what covering of the client (like a towel or sheet) must be provided.
If the massage in question involves massage of parts of the body the local law prohibits being touched, the local law will also state what penalties may be imposed on the masseuse or client or both. In many jurisdictions, these penalties include potential arrest for prostitution and/or solicitation of an act of prostitution.
