A system has been disclosed which allows improved sexual interaction between two individuals who are in separate locations or between one user and computer game software. One component of the system measures the displacement of a fluid that occurs when an object is inserted into an orifice to create digital data, which data can be transmitted to a remote location or used in software on the local computer. Another component of the system responds to a data signal that is received from a remote location or generated on the local computer and generates thrusting movement of a phallic object which movement is related to said data signal.
