Concentration is the key. Some women have their thoughts drifting away while having sex. Do not think of the unwashed dishes at the sink or the business report that needs to be done during the night. Sometimes, these thoughts can adversely affect sex. How can someone achieve the full orgasm if her thoughts are not really into the moment of sex? You have to be at the moment. Feel the passion and the heat while having sex. Embrace the moment with your partner until you reach the orgasm without necessarily waiting for it.
