  1. During intimate arousal, chemical element oxide (NO)
    is released from brass terminals and endothelial cells in the principal cavernosum.
    NO activates guanylate cyclase to change over guanosine triphosphate (GTP) into cyclic guanosine monophosphate (cGMP), triggering
    a cGMP-dependant cascade of events. The aggregation of cGMP leads to smooth-muscle easiness in the
    principal sum cavernosum and increased rakehell flow to the phallus. http://lm360.us/
