about blood flow

I want to mention a theory I read in this wonderful site (I don’t remember where) about the penis blood flow.

I read that blood flow depends on the blood pressure in our arteries going through penile tissues. So I think that the blood flow could not be increased by jelquing simply because jelquing enlarges our tissues but can’t determine an amount of pressure. The hardness is determined by the ratio between inflowing blood and outflowing blood. In conclusion if your penis grows it will be necessary more blood to fill it but not more blood flow. Your pressure is always the same if you don’t change this ratio and so your hardness. This is what I read some weeks ago. What do you think about this? Is it in contrast with some physics principles?

On the other hand there are some theories asserting that when you grow you require more blood flow. What’s your opinion?

I read elsewhere that what makes the increase is our cells that hold the blood expanding. When you jelq it is forcing that blood to go somewhere as the penis becomes engorged and the cells that hold the blood expand.

Simneil, I have wondered about this theory of yours before. I thought if I had a bigger dick my erections might get weaker.

However I guess the body knows when your blood levels are low and can create plenty of blood efficiently to account for any gains, otherwise all the gainers here would have ED!

What happens is: the manual exercises gradually increase the delivery capacity of the penile vascular system. Veins/arteries tend to grow wider (sometimes they become more visually prominent, too); this process keeps up with gradual tissue growth and with the increased holding capacity of the cavernosal chambers, allowing a larger penis to become as firm as the smaller one did.

Wow, thanks avocet, we can allways rely on you to inform us of the goings on down there. Your knowledge is very reasuring, I especially liked your thread on the ejaculation process, if anyone hasnt read it - do it now.
