A stimulator apparatus for stimulating an organ, such as a penis. The apparatus includes a spherical housing configured to receive an organ through at least one aperture and allow for a 180° range of motion while manipulating the organ and/or the stimulator apparatus. The stimulator apparatus provides intensified sexual stimulation through frictional engagement between the organ and at least one channel in the housing. The at least one aperture includes a cover, and is sized and dimensioned to resemble a female sexual organ. The at least one channel includes numerous textures, orientations, diameters, and mechanical features to help enhance sexual stimuli for the organ. At least one grip portion positions on the housing to allow for sufficient grip for a user to manipulate the stimulator apparatus to a desired intensity and duration. The at least one grip comprises multiple indentations that match each finger.
