Wondering where the spark went in your relationships? Find it in the bedroom. Sex is a great way to spice things up and make your relationship stronger. The female partner lies down on her belly at the foot of the sofa. Her arms are bent at the elbows and placed in front of her head. Her hips and buttocks are raised up and rest against the seat. The man stands over his partner with his legs spread wide apart and knees bent a little. With his hands, he takes his mistress by the shins and lifts them up to place her feet on his thighs.
