When partners experience sexual arousal from the acts of foreplay, their organs that are susceptible to pleasure become highly sensitive to external stimuli all while at the same time releasing bodily fluids that lubricate the organs to prepare for intercourse. For male partners this leads to an erection and for female partners this results in a clitoral erection.
Physically, the sexual organs for both partners receive more blood flow and become aroused.
Foreplay has important physical and psychological effects.
