Cialis is not commonly used in women because the tissues women have do not produce the chemical that is used in the process of erection. This type of chemical is only found in men and it makes sure that the valves in the penis are open wide enough to allow in more blood and make sure that they are closed after the chambers that stores it are full and no blood would be allowed to go out after they close. The chemical produced by men is always broken down by the necessary body organs to speed up the process of erection. However, women have tissues that are spongy like which are filled with blood and in this case blood is allowed to flow in and out of the tissues but not trapped in the chambers as in the case of men. The blood that is trapped in the arteries to the penis is important in making the person erect and keep it erect for as long as he is sexually engaged, but in the case of women if the blood is to be trapped in the tissue it will cause harm and can be very dangerous. With the usage of cialis, one is assured of long erection and under normal circumstances, an erection does not come on its own and this drug does not cause stimulation or an arousal. One has to be sexually stimulated to hasten the work of the drug for better result and if one is stimulated but lacks the desire or the urge be involved sexually, then the cialis comes in. |
