My background is surgical -- I've operated on male pelvic anatomy extensively, including critical care cases involving scrotal and perineal trauma -- so I understand the neurovascular landscape here in ways that go beyond textbook. One thing almost nobody talks about: the frenulum (underside of the glans, where the head meets the shaft) is the single most densely innervated spot on the penis. Ignoring it and focusing only on the glans tip is like pressing random piano keys and skipping middle C entirely. Arousal plateau is real physiology. The nervous system needs sustained, predictable stimulation to build toward orgasm -- erratic changes in technique right when tension is building essentially "resets the counter." Consistent rhythm matters more than novelty at the critical window. Post-vasectomy patients specifically report heightened sensitivity during recovery because of temporary congestion -- this tells us that scrotal and epididymal pressure sensitivity is often underestimated during partnered activity generally. Gentle attention to that anatomy isn't just a bonus move; for many men it's where the real signal is.
