Tail bone muscle - between the tail bone and anus.
You must focus your mind in the tail bone and lightly contract the anus without disturbing your prostate muscle (commonly referred to as the PC muscle) between the anus and scrotum.
The simplest way to contract this muscle is: Open you legs, post a horse-rider posture, and squeeze your butts against the tail bone. Once you locate it with this muscle, you can practice this exercise with breathing.

I have found that the pre-cum secretion is associated with the estrogen level, like the female lubrication.
Plant Estrogen (Isoflavones), Soy Phosphatidylserine, grape seed extract, saw palmetto, pygenum bark, pumkin seed, nettle, and ginseng in ViaGrowth-IV can help produce more pre-cum fluid. They also increase the prostate's secretion and prevent the prostate tissue from overheating and drying up to improve the prostate health and function.
