Intensity: can vary during intercourse depending on the position, the partner, the level of lubrication, etc. Sexual positions play a large role in the level of intensity/depth of penetration thus making the level of pleasure either increase or decrease depending on the intensity. With your wife on top, there is likely deeper penetration and contact between the genitals causing you to ejaculate quickly.
