So long as you've stuck to that healthy eating plan or your man is an heroic weight lifter the Ascent to Desire sex position should be easy!
He stands with feet firmly on the ground hip width apart, knees slightly bent. She stands before him. As he lifts her onto him, she wraps her legs around his hips.
It may be useful to start off sitting on the bed and then turn round once lifted so she can put her feet down and help support the lift with the edge of the bed.
The weight should help with deep penetration as she moves up and down.
