Don't Jelq Cold. Don't think a shower is a warm up.
I’ve had to take a huge break due to being lazy.
Wish I had pictures to share.
Long story short…
Jelqu out of quick shower on the go not a good option.
Really intense pressure leads to blood blisters always in the same place that take about a week or more to go away. I’m thinking it’s a burst, or weak blood sack in my shaft.
I usually get it from intense wanking or sex. Some times combined with alcohol or or nitrates for blood pressure enhancement to penis.
Folks, your member isn’t invincible. Be kind to it when you’re exercising you lil guy. :(
