You can have sex with your partner in many different ways.
Most women like to be in the same position for some time, since most of them usually need a minute or 10 to come to a climax.
Changing positions every 3 minutes can be frustrating for her since she will have to start all over again.
There are several positions that are liked by most women and it is nice to know at least a few of them so you can give your partner, and yourself, a great time.
oWoman on top aka in the saddle; Just lie down on bed, or the floor and give the control to your partner.
Next to you being able to hold her breast and look her in her eyes while she's enjoying the ride, she will feel extra comfortable knowing she is in control of the movement and she will be able to stimulate the spots she wants to be stimulated.
oYou on top; Being on top while your partner lays on her back gives you the control and it is very important that you keep paying attention to your partner; does it hurt her, does she wants it harder, should you slow down a bit, etc.
etc.
oDoggystyle; When your girl is leaning on hands and knees and your behind her you can continue the same motion for a long time.
Most women love this position.
You as a guy can also grab her breasts and play with her while you are busy.
oIn heights; You could also choose to have sex while you stand.
You can have your partner wrap her legs around your waist and you can hold her body and move her up and down.
