Jelq after waking up with no warmup

Just thought about to do a little jelqing routine in the moring in my bed before I get up.

About 5-10 minutes of jelqing with no warmup before.

I think that when you wake up, your dick is warm enough and also ready to go because of the erections you had in the night(I read that you can be up to 4 hours erect per night)

What to you think about?

Another thing:

How about a little edging as a warmup? I think having an erection for about 10 minutes should be enough to prepare the penis for a jelq-workout. Blood flow is ok, penis is warm. Then let the dick go back to your normal jelq state(50-80% erected) and start jelqing

I use lots of heat in my routine, so I wouldn’t do it just because it doesn’t feel right without heat. I don’t think you will get injured by not using heat. I do think you will cause more discoloration from jelqing without a heat warmup.
