Simply put, the G-Shot® is a treatment designed by Dr. David Matlock to augment a woman’s G-spot. So, technically, the name of the procedure is G-Spot Amplification®. The G-spot (“G” for German gynecologist Ernst Grafenberg) is an erogenous area inside the vagina that experiences intense sexual arousal and sexual gratification. However, the feeling and level of intensity are different in every woman.
