A sex pillow is an accessory that is often used to enhance foreplay and sexual intercourse. Often made from high-density foam and polyurethane, sex pillows can also be used to adopt different positions. These accessories can come in various shapes to provide adequate support for both partners. Most of the time, sex pillows are placed under the woman’s lower body to provide deeper penetration during missionary sex. They can also be used to enhance oral and rear-entry sex. Sex pillows are readily available in most sex shops.
