For women, it's all about the angle when it comes to reaching orgasm during penetrative sex.
So here are the finer points about the sex positions that really hit her pleasure zones perfectly.
Firstly, the main principle is to apply pressure to the upper inside wall of the vagina. A good way to know it's the right place is to check where her clitoris is and then aim to apply pressure gently inside and upwards towards it.
The oldest position in the book
While the missionary position gets bad press for being a little boring, it's one way to get the right kind of pressure to a woman's erogenous zone.
More importantly, it's a position that offers a good amount of connectedness during sex - something that most women really love.
Place one or two pillows below her lower back to give her support and to hit the right spot during penetration.
Depending on what you both like, she can rest her legs on your shoulders, or simply just behind you.
Now, gently support her buttocks by slipping your hand between her and the pillows. This way you can thrust upwards and inwards, lifting her at the same time - achieving deeper penetration and better contact with her internal pleasure zone.
Turn doggy to froggy
Penetrating her from behind mostly means less direct contact with this vaginal pleasure zone, but with a little adjustment doggy style can become a lot more effective.
Get her onto all fours and ask her to lower herself right down so that she is lying on her front with her legs spread out like a frog. Lift her torso up and place a pillow underneath her stomach for support. When you enter her, lift yourself up as high as you can so that your hard-on pushes down towards her upper vaginal wall.
Ride 'em, cowgirl!
Another great way to hit that inner pleasure zone is by getting her to mount you and then let her lean back so that your hard-on applies pressure to her vaginal wall.
Explore each other and keep checking what works best for both of you when it comes to giving and receiving pleasure.
Penetrative sex isn't the only way to enjoy each other, but it is a whole lot of fun and a great way to bond - just make sure you both use lots of lubrication to ease things along and avoid any unnecessary chafing.
