a.k.a. Head RushBenefits: The blood will rush to his other head, too.Move to the edge of the bed and have him lie back with his head and shoulders on the floor as you straddle him. The blood will rush to his head creating mind-blowing sensations as he climaxes.
The Curled Angel (aka Anjou-style) - karmasutra sex position
The woman curls up on her side, knees drawn up and the man spoons her from behind. Penetration is fairly easy from his position and the man can rach around to play her breasts or clit. 
Especially to recommend for pregnant women, this can be adapted so that she doesn’t have to bring her knees up quite so far and thus avoids squishing her “bump”.
The Splitting Bamboo
We usually refer to the man “getting his leg over” but in the Splitting Bamboo sex position the roles are reversed.
The woman get her leg over one of the man’s shoulders. The man straddles her other thigh and enters her using his hands to support her elivated leg and support himself. As her hands are free she can show her clitoris a little self-love or stroke his penis as he moves in and out.

The padlock
She climbs onto a high piece of furniture (work disk, washing machine …), sits down on the edge and supports herself with the arms behind her. He stands before her and she wraps her legs firmly around his hips as he leans in to penetrate her in the Padlock sex position. 
They can look into each other eyes as he uses grips her bottom to control the momentum. Time with the spin cycle for added “ohhhh”.
SPD: G-Spot Jiggy

Get down on all fours with your man kneeling behind you and have him plunge inside you, grabbing your rear for balance. A little firm, well-placed stroking of your G-spot can open up a whole new orgasmic world. If he’s the exploring kind, encourage him to thrust far enough inside you so that his testicles hit your body.

Why You’ll Love It:
Once you have a G-spot orgasm, you’ll crave more. Also, there’s something very primal about doing the deed from behind that brings out the animal in even the most mild-mannered guy.
If the doggy-style pose doesn’t make you hot enough, accessorize! Using a vibrator will definitely amp up the action. Plus, bringing a toy between the sheets could take your relationship to a whole new level since a touch of taboo is always a turn-on.

Have your guy sit on the floor with his arms stretched out behind him for support and his legs crossed loosely Indian-style. Climb onto his lap so you’re straddling him in a kneeling position and hold on to his shoulders as you lower yourself onto his erect penis. Lean toward him and keep your bodies close together as you take control of the timing and speed of the thrusting…. Ride him, cowgirl!

Why You’ll Love It:
This is the ultimate girl-power position, because you command the action by alternating slow, shallow strokes with deep thrusts. To mix things up more, lower yourself down your man’s shaft in drive-him-nuts circular motions (like a corkscrew), and this seriously simple sack-session becomes one wild ride. You’ll be facing him, so the hot and heavy eye contact will make the action extra steamy.
With you in charge of the speed and depth, you can tease the supersensitive head of his penis and tantalize the lower third of your vagina, which is packed with excitable nerve endings. Then, just when he’s about to explode in ecstasy, take his entire penis inside you for a sensational surprise.
