Bebop,
When I started hanging at the various angles, it took a while before I could hang truly BTC. I had to stretch the skin at the base and a lot of lig before I could go that far. I think most guys are like that. Maybe not.
Anyway, I would start out sitting up straight with a straight out angle. Almost 90 degrees. Then I would slide down in the chair a little more each day, lowering the angle of hang. The further you slide down, the more length in the seat of the chair you need.
Soon, you slide down far enough that the skids of the hanger can go over the edge of the chair. The seat needs to be the correct length so the penis does not bend under the weight. The skids can ride on the front edge of the seat as you slide down and before it hangs free BTC.
If a guys chair seat is long enough, or dick is short enough, he will not need an extension. Funny though when you begin to grow, it is great to need to make an extension.
Also, do not discount the various angles of hang between straight out and BTC. I can feel a different stretch for about every 20 degree change in angle.
