The human sexual response cycle.
Among both sexes, the excitement phase results in an increase in heart rate, breathing rate, and a rise in blood pressure. A survey in 2006 found that sexual arousal in about 82% of young females and 52% of young males arises or is enhanced by direct stimulation of nipples, with only 7–8% reporting that it decreased their arousal.
