What can I do to fix my bendy penis? (Photo)

It depends on the reason your penis is bent. If it is due to a condition called Peyronie's disease, this has to be treated first.

If your penis has a slight curve to the left or right when erect and isn’t painful, it is likely a normal anatomical anomaly and not a problem. In fact, most men’s penises curve slightly when erect.
However, if your penis has a drastic curve that causes pain during an erection, you may have a condition called Peyronie’s disease. This happens when scar tissue builds up and causes your penis to curve. This can be up, down, left, or right depending on where your scar tissue is located.
Most men with Peyronie’s disease are middle-aged or older. Having diabetes-related erectile dysfunction also puts you at a higher risk.
There are treatments for Peyronie’s disease as well, so talk to your doctor if you are concerned about the curvature of your penis.
Prometheus by Dr. Malik has also helped men with Peyronie’s disease improve the look and size of their penises.

Thank you for the photo and the question. A combination of fat transfer along with platelet rich plasma can improve this condition, which looks like Peyronie's. It may require a few sessions, but the stem cells inside the fat and growth factors inside the platelet rich plasma can help remodel the penis and straighten it.
