I think you need to take yourself to the bedroom or bathroom all by yourself and learn how YOU can make yourself orgasm! I'm so depressed when I heard of women who have never masturbated!!
1. The clitoris. Stimulate it with your fingers! Or maybe a water sprayer. Or perhaps a vibrator. Try it out! 90% of women (that most likely includes YOU) orgasm due to clitoral stimulation, which has nothing to do with penetrative sex. Yes, it's true! You can orgasm without a penis inside of you!
2. Spend the time along to figure out exactly what makes you feel good. Again, pay attention to the clitoris. Try side to side. Try making circles. You'll eventually find what feels good.
3. Don't stress at how long it takes; enjoy it! Most women take 10 or more minutes to orgasm! This is going to be a marathon, so make sure you're comfortable. This is why many women have vibrators: their hands get tired!
4. Only once you can orgasm by yourself should you have sex again. I'm not kidding. You need to discover yourself as a sexual organ before allowing something else in the picture.
5. Stimulate the clitoris DURING sex! It's okay to do this! In fact it feels really freaking good! I suggest it t every woman.
