4 must-try sex positions

Making even subtle changes to your current 'go-to' list can mean the difference between a sex life that's fine and one that's on fire

When it comes to sex positions, after a while it's only natural to fall back on your old favourites. And there's nothing really wrong with that, except that, well, it's kind of dull. So mix things up! Experiment! Surprise your guy with something unexpected!

Digging Deep sex position

We're most familiar with man-on-top positions. They're great for gazing lustily into each other's eyes. And as an added bonus, they're terrific for deep penetration. For fans of deep, intense penetration and enthusiastic thrusting, you can't beat this position.

With this variation, the top half of your body can't move much, but you can make up for it by moving your pelvis both up and down and side to side.

First, lie back on the bed with your torso and bottom on the bed and your legs resting on the floor. When he penetrates, you bend your knees back toward your stomach while he supports himself on his hands and thrusts forward. It's best for him to keep one of his legs on the floor for support and the other on the bed for balance.

If it still doesn't feel like he's penetrated deeply enough - you greedy girl - pull your knees even further back and rest your calves on his shoulders, or, heck, show off by demonstrating just how handy that Pilates class really was by crossing your ankles behind his neck. Add extra frisson by holding your own hands above your head to give the illusion you're tied up. Better still, get him to actually do it!

The Sex Squat sex position

Urgent, animal and aggressive, rear-entry positions are used by most couples when they're both massively turned on. He can thrust more powerfully here than in any other position, and while some women flinch at the thought (Ouch! You just hit my cervix!), most are huge fans.

Because you can't see each other, it's great for fantasising (being unfaithful is obviously much better in your head than actually in your bed). And although it looks energetic, you can respond as little or as much as you like.

Up the lust level by doing it in front of a mirror, or vary it by alternating between leaning forward on your forearms and sitting up straight, leaning back and letting him kiss your neck.

For my new twist on that old favourite, you'll need a chair, and it's important that it's sturdy. If you can, secure it against something or put it near a table or window ledge (a good idea, maybe, to draw the curtains while you're there), which he can grab onto to keep things steady.

Once that's set up, you stand on the chair facing away from him, then get in a squatting position with your hands on the back of the chair for support. He puts his hands on your waist or clasps the top of your thighs and penetrates gently.

It may help if he puts one leg on the chair to keep it steady while leaving the other on the floor. As I said, keep it s-l-o-w. Move your bottom from side to side for a unique, intense sensation.
