Jelqing without stretching?

I was wondering if a routine of warming up with the shower and and a wash cloth and then just doing jelqing is safe. I can’t tell from forums whether the stretching is for warm up or just another kind of exercise of PE. While jelqing appeals to me, something about the stretching does not, and I’d rather just do the jelqing if it is safe.

Stretching is a PE exercise targeting length mainly.

I’ve just jelqed for a few months and I’ve gained great EQ, length and girth.

You can add stretching later if you want.
