Brand Viagra affects the response to sexual stimulation. It acts by enhancing smooth muscle relaxation using nitric oxide, a chemical that is normally released in response to sexual stimulation. This smooth muscle relaxation allows increased blood flow into certain areas of the penis, which leads to an erection.
Viagra is applied for the treatment of erectile dysfunction (impotence) in men and pulmonary arterial hypertension.
No more than one should be taken in a day.
If you are young then there is not any need to take Viagra!
50 mg Viagra is the recommended dose.
100 mg is the maximum dose for brand name.
Before taking Viagra, don't drink grapefruit juice! This reduces the effect of Viagra.
Massage is recommended in traditional Chinese medicine to unblock the patient's meridians, stimulate the circulation of blood and qi, loosen stiff joints and muscles, and strengthen the immune system.
Because all the pressure and the blood goes into you penis when you are seein something sexual.
If you mean the foreskin getting stiff, you need to clean your head more and maybe start gently masturbating If you mean your whole penis getting stiff it is because of the blood rushing to it when you become sexually aroused...
Most of the time, you are tearing your muscle! Believe it or not, in order to get stronger, you need to tear your muscle. But sometimes, when your arm or leg is stiff or doesn't look right, it means you pulled it.

My penis alright *gigedi gigedi* an erection is when the penis gets stiff, you jerk off, feel good.

Stretching...and maybe painkillers?
spasm and twitching of muscles, particularly the jaw muscles become stiff
YES i have had stiff neck all my life and have been reserching and i have found that it was my spinal cord
rigor mortis
Yes it loosens up muscles and prevents them from tearing. Cold, stiff muscles tear much easier.
