The best sex positions are the ones that are pleasurable for the both of you. Of course there will be positions that feel better for yourself or for her. And as a good lover, you'll want to put in that extra effort once in a while to make her feel great during sex even if the position isn't that great for you.
A common sex position is the one with the woman on top. Women tend to enjoy this position more simply because they have more control and thus are actually able to cause themselves to orgasm. Now while this position means that the women have to do most of the work, this doesn't mean that you should just sit there and enjoy the ride. A great lover will be a participant of sex at all time.
What you can try doing with this sex position is to sit up against some pillows so you'll be able to kiss her during sex. You should also add to the thrusting motion or play with her breasts. If she's not use to being on top she might have some problems finding a rhythm and there's no harm in helping her with that. Part of great sex is exploration so try to find something that you will both enjoy.
From the back or more commonly known as the ‘doggy style', is another sex position that both men and women seem to enjoy. It's a favorite because men find it easiest to hit the g-spot from this angle. The only thing you need to be careful about is thrusting too deep (and this will happen because you have so much freedom to move around) because you could actually hit a woman's cervix. This can be quite painful and it's something you should avoid.
Apart from just thrusting in and out (and finding a good rhythm in this position), there are loads of things you can and should do with your hands. From the back you are able to easily play with her breasts or stimulate her clitoris. Do this right and you can really create great pleasure for her.
A variation form the doggy style sex position is simply doing it from the back. You could have her sit on you, facing away. This position is great because it allows your hands to roam and she's partially on top which means that she gets to set a rhythm that she enjoys. To make things even sexier, try doing this in front of a mirror. Some couples find it highly erotic, but it's not for everyone so make sure that your partner is comfortable with it or the sex will be too awkward and hardly enjoyable for the both of you.
Finally, the basic and safe sex position is of course missionary (man on top). You'll have to do most of the work in this case and sometimes men really enjoy this position because they're the ones in the driver's seat. In this sex position, women will receive clitoris stimulation from the base of your penis so be sure to figure out how to hit it.
Your hands will usually be busy keeping you balanced so what you need to use is your lips. In case you didn't know, women can be extremely reactive to kisses not just to her face or her lips. So try nibbling on her ears or her neck, try discover if she has any secret g-spots around her face and ‘attack' them in this position.
