Well, the ratchet beneath him obviously pulls his balls, so a few clicks on that will make him push his groin area forward if he can, adding strain on his arms again. It looks also that there is something pulling the front of the hood, not sure. If that's so then that's another area for a ratchet perhaps and makes any head movement difficult or impossible. Pulling upwards on his arms makes the ache worse. been there done that :) only I was standing. Legs forced apart leaves him open to a load of fun.
