Yup.
It helps to be very aroused before sex or masturbation. It helps to feel completely relaxed without any stress. It helps to have a long period of foreplay, but only if it's good. If you're male, you can increase your partner's sexual pleasure by asking her to show you how she masturbates. For a woman orgasm is about more than just rubbing the clit and it will happen. The motions, pressure, lubrication, and things like that all matter. So ask your partner what she likes, and to show you, and that will make sex better. Another thing you can do is to get her close to orgasm, and then to stop a while. During this time, she can give you a blow job or you can do other things. Then start again after a while. By the time she finally climaxes, her orgasm will be much more intense.
