louiecock, don’t end up with the name lazycock. Or lewdcock.
After surgery like that your penis would be longer, yes. It would also hurt like hell for weeks-monts, your penis will never point up again, and visually your balls would hang somewhere halfway your shaft. I seriously doubt erection quality would be good afterwards. And to make matters worse you could get scar tissue on both ends of the ligament, perhaps shortening total length.
Edit: I just realized that that ligament, as all ligaments in the body, is just a thickening of a “sheath” of fibrous tissue. So it’s not really a cord you can cut, just a thickening in a larger tissue layer that can be cut and afterward you need to take care to make sure it doesn’t grow together again. While repair would be slow, you’d just end up with something that I can only describe as fucky.
Don’t.
