Testosterone

b/c increase human female receptivity, even during non-reproductive periods of cycle

...Tegmentum (esp Periaqueductal Gray Area) > Basal Ganglia > SBN for rhythmic contractions, as in males

5

Periaqueductal Gray Area

produces Endorphins, including to suppress Pain

6

Dopamine to Nucleus Accumbens for reinforcement

7
