An apparatus for use in performing intercourse, including: a horizontal support designed to support a female in the supine position a bearing assembly attached to the outside of the horizontal support and a base horizontally slidably attached to the bottom of the bearing assembly. The bearing assembly is designed to permit rotation of the horizontal support about the axis of rotation of the bearing assembly. The horizontal support and bearing assembly are designed so that this axis of rotation is coaxial with the longitudinal axis of the sex organ of the female when she is supported on the horizontal support in the supine position. The heights of the horizontal support and base are adjustable. Thus the height of the females sex organ can be adjusted for penetration by a male partners sex organ when the male partner is standing at the correct end of the horizontal support.
