I managed more than two minutes this afternoon. The second rope at the side, to lower and raise manually, is a good help.
I can feel the longer stretch, because the part between my balls and arse-hole is slightly sore! My balls aren't, though.
I think I'll raise the rope even higher, because my head still can't drop down freely without my touching the floor.
I'm having trouble reducing the size of Habakuk's graphic instructions in a previous blog, by the way. I can only apologize; and I'll try again.
