n.[解]小系带；[昆]翅缰
Make a twisting motion with one hand as you slide it up and down, and swirl your tongue around the rim of the head, paying particular attention to the frenulum. 嘴上下滑动时，手要不停打转，并且，舌头绕着龟头打转，特别要关注一下包皮系带。
The frenulum is innervated both by somatic and autonomic nerves, the somatic nerve is derived from the penile dorsal nerve and the perineal nerve, the autonomic nerve comes from pelvic plexus. 包皮系带接受躯体神经和自主神经双重支配，躯体神经来自于阴茎背神经和会阴神经，自主神经来自于盆丛。
