The ins and outs...
You: Lying on your back with your legs tipped in the air.
Him: On his knees in front of you, he takes your legs and places one on each side of his neck to rest on his shouders. He grabs hold of your hips firmy and leans in towards you. Clinging onto him, you'll be rocked by a very sensual swinging movement.
Why is it so good? This position causes the vagina to open up wider to accomodate your partner's penis, something he'll appreciate! It also leaves your hands free to wander. Use them to caress each other while looking into each other's eyes.
A good time to try it: When you feel supple enough to hold the position and for those moments when you want to embrace him mid-action.
Tip: Your vagina is more open in this position, so you can have fun contracting your pelvic floor muscles during love-making. Squeeze the muscles around his penis then let go, and repeat. He won't know what's hit him!
