erection
It is called an erection.
An erection is when the penis becomes filled with blood. This causes it to become larger in size and hard. The purpose of an erection is to allow the guy to have sex and reproduce.
The penis becomes erect though hormone-induced blood flow to the genital area. The area wouldn’t get completely erect if there is a lack of blood flow. This lack is due to a compilation of things, including genetics, stress, and diet.
No. Blood stops running through the body when ur dead. Which means blood can't go to the penis.
Penis (in men) Clitoris, nipples (in women)
No that is not the way it works Your penis would have to be enormous to have any effect on the rest of your system. You see if yous blood supply was not big enough to supply your penis it just would not get hard well before it killed you.
Penises become hard by inflating the organ with blood. This means that when large the veins in the penis are visible in may cases.
Hell no, because then they would always be hard. It's when the blood vessels in the penis pressurize
That would be a Boner. Its not really a "Bone" but when blood floods the flaccid penis it becomes hard and erect. Common name for this is a "Boner", in the scientific world it is called a skeletal muscle, because its like a skeleton bone but its a muscle. These are facts.
Could be in the penis, could be in your head. The penis is there to send stimulation to the brain. If we are not in the mood or we are worried about something, it is hard to get hard. Could be a physical issue, high blood pressure, diabetes. Go to a doctor and find out. Not getting erect could be a sign of something more serious.
just like you fill air in tyre tube when you are sexually excited your penis has spongy like tissus which fill with blood and your penis get hard after some time it start shrunking and obtaning its orignal position
It relaxes a muscle that acts like a valve that's keeping the blood flow away from the penis. When the "valve" opens blood rushes out in the penis causing it to inflate and grow hard just like when a balloon is inflated.
