Hi there and welcome to Thunders.
Ok, you say you’ve jelqed on and off for 6 months (give or take). My advice is to begin following the newbie routine, even though you have done some exercieses. On and off doesn’t get it when it comes to enlarging your penis. It has to be a dedicated activity that you commit to . Breaks are allowed, but they usually come with a plateau and resting for a while then starting again will sometimes “shock” the penis into growing again.
I would not recommend hanging until such time as your penis is conditioned. Injuries are no fun, and they really hamper gains as you can’t do anything until its healed. An ounce of prevention really is worth a pound of cure when it comes to Penis Enlargement. As I said before, following the newbie routine and condition your penis first, then add hanging.
Good luck to you and keep us posted. Read a lot here, much valuable information is contained, use the search function to find those hard to find answers and when all else fails, ask questions—we really do answer them (West sometimes grumbles, but he always answers).
