Editing Sexual stimulation (section)

=== Brain ===
When sexual stimulation is perceived, there are systems in the brain that receive the stimuli and respond to it. During physiological sexual arousal, the [[autonomic nervous system]] responds to signals from central nervous system and prepares the body for sexual activity.<ref name=":10">{{Cite journal |date=2011 |editor-last=Mulhall |editor-first=John P. |editor2-last=Incrocci |editor2-first=Luca |editor3-last=Goldstein |editor3-first=Irwin |editor4-last=Rosen |editor4-first=Ray |title=Cancer and Sexual Health |journal=SpringerLink |language=en |doi=10.1007/978-1-60761-916-1|isbn=978-1-60761-915-4 }}</ref> The autonomic nervous system engages the parasympathetic and sympathetic systems, which are responsible for blood flow to genital and erectile tissues, and to muscles that participate in sexual responses.<ref name=":10" /> This results in responses like increased breathing rate, heart rate, and pupil dilation.
