English is not my native tongue either, so be patient.
IMO, stretch then jelq is better. I myself has a theory about it.
Most of us has a longer FSL than EL, the difference is that you pull manually with fingers to get FSL, while you need blood to get EL. And many of us also gain FSL then EL, and we also believe (at least I do), FSL gain is a sign of EL gain.
So, after stretching (for FSL gain), you pump your dick with jelq/clamp so it will accomodate more blood, and it will translate FSL translated to EL in the future.
And I also believe the rubber-band theory.
I only know a guy (forgot his name, I think it’s Mr. F) who doesn’t do jelq but only hanging and ADS, and grows.
