With coital alignment, both partners rub or grind up against each other’s bodies to create friction against the vulva. It's all about putting a substantial amount of pressure on the clitoris. Once this is done for a substantial amount of time fluid is released from the Bartholin's Gland. Bartholin's glands secrete mucus to provide vaginal lubrications during sex. The fluid may slightly moisten the labial opening of the vagina, serving to make contact with this sensitive area more comfortable. Shop online www.theppgstore.com
