Robin Williams once said "God gave men two heads and only enough blood to work one at a time". Might help yall conceptualize that the penis has a "brain" of its own. The erotic dreams, reading and viewing erotic material all require input from the brain to reach the penis whereas penile stimulation is a local reflex.
Worth noting that not only is there a separate reflex arc for non-psychogenic ejaculation, but that glandular secretion, emission (contraction of everything besides the penis muscles), and ejaculation (contraction of penis muscles i.e. ischiocavernosus and bulbospongiosus) are all under reflex control.
-- All efferents are parasympathetic EXCEPT for emission (sympathetic) and ejaculation (somatic). -- all afferents are pudendal n. except for psychogenic erection which starts with higher centers
