Not all sex positions are best for getting her to orgasm. To improve the likelihood of having your partner orgasm for you, she will need some sort of stimulation to her clitoris and not all positions make this possible.
While these positions might be fun, they are not the best if your aim is to provide her with the best orgasmic ride of her life.
Missionary Position: The reason why this does not work is because this does not make room for stimulation of the G-spot or clitoris. But this does not mean you should give up on the move. A little adjustment and you are good to go.
Instead of lying flat on her, raise your upper body up so your chest is near her shoulder and to the side. This will cause the base of your penis to rub against her clit as you move.
Doggie style: This focuses on her behind, and since all her fun, sensitive parts are more to the front, she is unlikely to cum for you. To make her orgasm, encourage her to touch herself and massage her clit while you enter her.
Standing up: While this often look fun in movies, it does not really work for women in real life. It is rare to find a woman who will climax through standing-up sex, since she is so focused on maintaining balance, and if you are lifting her, she is hoping she does not fall. This position is great if you want to be sexually adventurous, but does not do much for a woman who wants to orgasm.
Anything complicated: If you have to read a manual while having sex to get a particular position, then she is unlikely to orgasm. For a woman to get there, she needs to be relaxed and she needs to enjoy what you are doing with minimal discomfort.
