First off, congrats on your size. You probably know you don’t need to grow, but who doesn’t—even a little!
I’ve heard stretchers do work. I’d like to buy one eventually. More because I’d like to unbend a curve a little and make the dick more flexible.
Great that your stretching is working. Do keep a progress report. You just don’t wanna overstretch. That’s what I’ve heard about that. Words of caution from someone who has had penis injuries in the past—they’re not fun

. I don’t know if you can gain an inch an a half in 4 months. That’s pretty substantial. You might get half of that, if lucky in beginning. You might get pretty noticeably bigger immediately though. You could be releasing a lot of your hardness that you’ve not seen in a while.
Are you doing anything else like jelqing or pumping? I wish you the best man.
I’m glad you posted this, because I was thinking about this today. I’m about 8.7 bp on a good day and curved a bit to right. I would love to find a way to get that quarter-half inch to be bonafide 9. But I’ve had a cockring injury in the past so worry about using things like pumps and bathmage. Wondering about real gentle methods.
I wish I could do it in a shorter time too, but might take longer if being good to your dick and trying not to injure it. Injuries always hold you back, and they can be very serious, as we all know.
Please share what products you’re using so we have a better idea your protocol/program. Thanks again for posting this—best of luck!
