My girlfriend should write a book on it. First off get ontop of him, once the penis is inserted fully into the vagina start doing a grinding action backwards and forwards.

It really isn't as hard as it may seem. I thought it would be also. I have a hard time with him entering while I'm on top, so I will lay down, and then he will pull me up (not the smoothest, but when it works... amazing ;) ) Try a few different ways to see what works... but when you get it, it's really fun! ENJOY

You could also try turning and putting your back facing him....that way you put downward pressure on his penis and get some clitoral stimulation from his scrotum....This position drives my husband crazy....the first time I did it he said "OMG....what are you do......." then a series of ahhhs and oohhhs!

I also agree that grinding back and forth is good, however, it usually more pleasurable for the woman when you grind....if you really want to drive your man crazy, straddle him and with your feet holding your balance bounce up and down gently so he can feel full penetration and the slide back off...gradually speed up and see how long he can handle that...

Good luck and enjoy yourself.....sex should not be stressful but pleasurable and fun....don't be afraid to ask your SO exactly what he wants but then be ready to follow through....he might suprise you and then again....you might just suprise him!!:p

Your boyfriend lacks tact and manners and couth.

Since you know what goes where and where where is, why not take what and place it where, yourself. That should make insertion easier.

Also, "grind", side to side and in a circular motion in addition.

Sorry to hijack, but I need some help on this too!

I can manage grinding against my bf while he's in me, but when it gets too fast I always find that my hips jerk to this grinding halt. It's so annoying but I don't know how to stop this. I can never last more than a minute on top.

Please help!
