Well no, prostitution is specifically the form of work that involves delivering sexual experiences to clients; just as bricklaying is the form of work that involves installing bricks in an organized fashion onto clients’ property. Bricklaying doesn’t normally involve sexual experiences, and prostitution doesn’t normally involve bricks, but both are work.
Prostitution is also performance work, which is a category that also includes acting, music, and pro wrestling. It is also body work (that is, the worker does something to the client’s body); which is a category that also includes massage, surgery, and hairstyling.
