Started new routine. Input appreciated

Old routine:

10 minutes stretching
5 minute warmup with hot water cup
600 jelqs (Super conditioned unit so not dangerous)

New routine:

5 minute warmup
15 minutes stretching
5 minute warmup
300 jelqs

After reading some things on this site and asking some questions, I decided to see if a less is more approach would work and at the same time focus more on length. To that end I now stretch for 15 minutes instead of just 10. I have also come to believe that a warmup before stretching and jelqing would be good versus a warmup before just jelqing. My girth is 5.5. I know that’s already big but my gol is 6. Last night marked my third night on the new routine and I think my EQ has improved somewhat since then. My goals with this new routine are to more specifically target length and gain better EQ. Any suggestions and input would be appreciated. Thanks! :D

What about warm down, I mean after your PE?

I admit I haven’t been doing that. I PE at night and since I go to bed right after PE, I figured it stays warm enough. Do you think it’s a mistake not to?

Yes it is!! Warm down is just important as warm up.

Warm up prepares you for workout and warm down refresh your unit and good blood circulation

Well, if you think so. I’ve been neglecting it because I just want to go to bed.
