Bathmate routine before/during /after and selection of bathmate - by: Dall87

Hello all,
I'm fairly new to PE and this website. Everything looks legit as far as reviews and testimonies. I'm in the process of deciding what bathmate to choose and my routine to expand, cement, and avoid injury/discoloration as much as possible. Here are my plans. Please comment with thoughts and suggestions:

I'm choosing the bathmate x30
Current size
NBPEL 5.25
BPEL 6.0
MSEG 4.75

Here is my plan as far as a work out:
Sleep with a heating pad on my dick
Wake up and stretch dick
Enter bathmate with as much water as possible with full erection and stetch for five minutes(will have to make adjustments as I get experience on how much pressure to use)
3 minutes of jelqing
Repeat 3x
Massage dick with some cream(I believe cortisone cream is recommended)
Wear cock ring for 30 minutes after
5 days a week.

One if my concerns during jelqing will be cumming as in my experience it's almost near jerking off. Would hate to blow a load before a work out and ruin my chance of full erection. Any suggestions?

Looking at all day stretchers too to apply further down the road.

Thanks guys!
