Does Stretching contribute to girth gains?
After much research, I finally decided to start a routine. My goal is to increase my girth by ~0.5in as safely as possible. My current stats are 6.5 NBPEL and ~4.8 meg. I figured In order to decrease my risk of injury, I would do a low amount of jelqs for the first few weeks and during this time both help condition for longer jelq sessions and learn about my penis and what effects jelqing has on it. My routine right now is to warm up with a hot wash cloth for 10min, about 5 minutes of jelqing and hot shower as a cool down. Over the summer, I will slowly increase the amount of jelqs. I use a mixture between the ok grip and the C grip for jelqing (just an okay grip but pretty much only put pressure on the sides) because I have read that this decreases the risk of nerve damage. I have decided not to incorporate stretches because I am happy with my length already and I think stretches is just another variable to worry about in terms of injury. Also it takes more time.
Is this line of thought correct? Will this routine of only jelqing with a C grip and not incorporating stretches help me towards my goal of a 0.5in increase in girth?
I have tried to provide all the information for my routine so please critique if you think there is a better way to achieve my goal of increasing girth while having the lowest possible risk of injury.
