How to do it: Both partners lie on their sides, your front pressing against her back like the spooning cuddle position. You're the big spoon, she’s the little spoon.
The receiving partner should separate her legs a little. The penetrating partner should find the vagina with their hand, and enter from behind.
Why it feels good: The short strokes target the g-spot, making it a great one for the receiving partner.
Focus on grinding your hips against her butt, and try some clitoral stimulation with your fingers at the same time.
The strokes available in this sex position will be very short, preventing the long wild thrusts that cause most men to experience premature ejaculation.
