MOST women can't orgasm during intercourse.

Try stimulating your clitoris during intercourse--that should help.

And STOP FAKING! He's never going to learn what's RIGHT if you keep rewarding him for what's NOT working!

I agree with all of the above that Synnen mentioned...

Also, make sure you are completely comfortable. With yourself, your lover, and the situation. You will never have an orgasm if you aren't able to focus on the moment. The least little distraction can prevent you from orgasming.

Make sure you're comfortable enough with your own body that you can convey to your partner what you want and what pleases you. Have him take his time with you so you can relax and enjoy the moment.

It is a shame that so many women can not have an orgasm and most men come to quickly.

Many women stimulate themselves, or get their partner to stimulate them if they want to have an orgasm during intercourse.

The other alternative is to have intercourse in a position which puts pressure on the clitoris and create a sort of rocking rhythmn which leads to orgasm.

The thing to remember is that we are all different and it's all about what works for you and your partner. Sex is like everything else in life - we grow and learn as we experience it.
