To achieve the best results when massaging the perineum, for females: Gently use your thumbs or 1-2 fingers to insert 3-5 cm into the vagina.  Then, firmly sweep in a downward and side to side motion for five minutes, using a natural oil for lubrication. Just make sure to avoid nut-based oils if you have allergies and steer clear of baby oil, mineral oil, or petroleum jelly.  If you experience a burning sensation, don't worry, it should fade over time. And remember, if you have active genital herpes or a vaginal infection, it's best to avoid massaging.  Oh, and many women find that involving their partner in the process is a positive experience. Happy massaging!
