is this ok for stretching?

I find that I get my best stretch session in directly after jerking the chain. My penis is as limp as can be and I get in a really good, long stretch. Is there any reason why this could be detrimental to growth?

No, I think that it is fine to blow the load if all you are doing is traction type techniques. however you could have a hard time getting an adequate pump if you do it before jelqs.

yes, only manual stretching. It is very weird. I am much more thick than long, so when my dick is just regular or maybe 10% hard, I can’t stretch it at all. However, after blowing a load and it goes totally limp, I can stretch it almost 1.5 times lengthwise more than if I just stretch it after pissing, etc. weird.

I have notice too that if I am hangin a little fat I have a hard time getting a good stretch. blowing a load beforehand would seem a reasonable solution as long as your jelqs for the day are already done. In your case I guess it doesn’t matter.
