i made it by my self, with a narrow long knife, cleaned it in boiling water, pulled my tail with a rope strong in length, and stitched the knife into the crotch over my the tails root, directly below the bone, where they will be fixed; then i made little cuttings across and could hear a hard scratching sound, when the knife sliced always a bit the very strong and hard ligament. with little slicing motions i moved the knife always over the tensed ligaments and could hear and feel so, that i was at the right position and tissue, a ligaments, i found them about an half until one centimeter - when i remember right - left and right of the middle my tail.
I made it in some sessions and each time the tail hung a bit deeper and longer.
But he will stand now never more in a right angle from my crotch and i have to heave up and steer him, when he shall slip into my wifes hole.
But because this will happen not so often - the last time some years ago - this will be no argument for me. its great, when my tail will hang now longer, its a good view for me and good in using with my hands...
I have a bit fear to cut more of the ligaments, because i dont know, if he will be still so good stand a strong pulling - isnt it?
A good male tail you can pull in length as like crazy and he will stand it well and also painless by his good ligaments, but if they will be capped totally, then the urethra could perhaps rip open or off and this will not be so funny, i fear...
here is a short vid of my cutting:
