Hi Joey:
Q1: ticktickticker, how exactly do you clamping for the head?
A1: As I said: I apply the glans ring while the dick is completely flaccid. Then a wrap at the base, one cable clamp very close to the base, when the erection goes down I clamp tighter and eventually will place two further clamps next to the other ones.
Q2: I am asking because I think clamping behind the head can be pretty dangerous (nerves).
A2: There is no clamp behind the glans, just a ring. Since the ring is round and the dick is oval, the pressure points will be at the sides (not where the nerves are running).
Q3: And for the cockring: If it shall be very tight even before one applies it, how can you get it off when the head is even bigger after a long session of clamping?
A3: once you take the clamps off, the pressure in the corpora falls and the volume, too. If you still have an erection, you will have to wait before you can remove the ring.
