It is called an erection.
Females do not have a penis, so they do not experience erections like males do. However, blood flow to the clitoris can increase during arousal, causing it to become engorged and sensitive.
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)
One is the swelling of the clitoris, a small structure in the vagina that swells with blood and gives females pleasure when touched. It's like the equivalent of the penis, but small (and it doesn't stick out, it's maybe a few centimeters long, although the size varies among women). Also, girls also get discharge, a clear liquid that comes out of their vaginas when aroused and when they orgasm. Sometimes, their nipples also swell and harden.
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
When the penis becomes hard, it fills with blood and stretches the tissues, causing a sensation of pressure. Once the erection subsides, the tissues relax back to their normal state, which can cause a stretching or pulling sensation. This sensation might be interpreted as pain by some individuals.
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.
