Acouple should take its time like an hour before theye have sex. This gives a woman time to get into her sexual moods. This also helps her to time the ejaculation from both sides, whereby no one finishes before the other. The reason for this is because this leaves one burning as well as failing to enjoy the game.
Normally men ejaculate before the women. Turning her on first helps the whole process half way, then the party gets started because both parties would be able to finish and reach their climax att the same time.
