okay ladies, here's my success story. i dated a guy for three years who i could never get off on top. i was so frustrated by it, felt inadequate sexually, the whole works.... my second relationship was totally different. i got him off very well, and the trend has continued. from this, i learned two things:
1. some guys just don't get off from a girl on top
2. with the guys that do, there are some sure-fire tips:

Try a jackhammer motion. Thrust your hips up and down on his penis so that it is standing tall and you are moving up and down vertically on him. It's kinda like doing a push-up, if you're envisioning it.

Less skin contact is better. If the penis-vagina contact is the only point of contact, he seems to cum harder. Also, keep it up for a while. I know you probably feel like your legs, hips, knees, and lungs are going to give out, but it takes a while to build him up to it.

Get into it yourself. Moan, tell him how amazing he is, how wet he makes you. Get explicit. When you're in an on-top position guys like when you take control.

Good luck. And remember, not getting him off when you're on top is not a failure.

to give the guy pleasure, he can hold ur bum and push u up and down on him. this gives him nice penetration and will make him orgasm in no time hehe i love woman on top!

On the rare occassion that my wife does this, she straddles me, and has to guide me in. I dont advise starting intercourse off this way, best to be REALLY well lubricated before you do...

once we're..."together", she usually leans forward a bit, and moves at an angle, both back and forth and up and down. We find that this also gives me room to thrust, and when you catch the rythm it's very good...if the male thrusts while she is coming back down, it is a tremendous feeling.

I think women on top is a very erotic position. They can go as fast or as slow as they want and tease their man that way. You can slide up and down his shaft or just rock back and forth on it some. Mix it up! I, personally, like to sit up straight, with my feet down on the bed (or whatever!) and pretty much do squats up and down on his cock. You can hold onto his hands for support or the headboard, if you can reach it. When you do that, he then has some room to thrust up and meet you...

being a virgin is definately nothing to feel embarassed about. its something to be proud of. i wish i was sometimes and i definately prefer guys with not much experience

I was a virgin until age of 22 and I was proud to be one, it made my gf feel special.

As for girl on top, I love this position as it is a great turn on. But yeah, we had real dificulties with it to begin with and I would always slip out at the heat of the moment, this still happens but less slow. The trick was I would have to lie most still and avoid to much pushing and let her do all the work, she loved leaning back putting her hands onto my knees for support. However, rarely would we finish like this, we would often switch to missionary or doggie.

Best thing is just practice and communication

Hi welcome to the board.
Try this LINK.
Should be helpful.

Also, you really didn't have to be embarrassed about being a virgin. I mean as much as you might not believe it... they still do exist, lol.
I was one till I was 22.
If your boyfriend new, they he might be better able to help you along and guide you. Even if you want to contine the "not a virgin" story. You could tell him that the guy you were w/ before was always on top and you never really got any practice being on top.
Good Luck

I was going to ask the same question! So yeah any help would be appreciated by me too! i find it a little awkward being on top, i generally just move my hips back and forth but cant seem to get a rhythm happening.

By the way I'm new to this site too, ive been reading the boards a bit though and everyone seems really friendly and helpful. Seems like a nice community you people have got here! So hey everyone, I'm Mia!
