A surfboard sex position is a man on top position where he can conveniently enter the woman through her vagina or her anus. The woman lies flat on her stomach with legs straight on the bed, and her head turned on her right side. Her arms are positioned slightly above her head.
The man squats on top of her bottom and holds on to her shoulders. The man is in complete control in this position, though the woman can arch her back a bit and lift her bottom to meet his thrusts.
The man can also reach beneath the woman’s torso and fondle her breasts. If the woman can lift her body, he can reach into her clit and provide stimulation for her. Or she can reach down and stimulate herself while the man pounds into her vagina or anus. This sex position can be tiring for the man.
