Sexual pleasure begins in your brain



Your brain and nervous system control your sex glands and genitals. This is why they also control your sexual desire, as well as orgasms. It explains why, for example, visual images trigger sexual desire in both sexes.

Your brain stem also emits nerve impulses that control erectile function. These nerve impulses navigate through the erection center of your spinal column to the erectile tissue of your penis where they trigger a chain reaction in the membranes of your vascular muscle cells.This sophisticated chain reaction depends on a messenger molecule called cyclic guanosine monophosphate, or cGMP.

However, this works in reverse as well. An erection softens as soon as another enzyme called phosphodiesterase starts to degrade the cGMP molecules.

Drugs like Viagra, Levitra and Cialis work by inhibiting phosphodiesterase, which may help maintain your erection. But, these pills will not lead to an erection. Your initial erection still has to be triggered psychologically. Without that initial impetus, potency pills will have no effect whatsoever. This is also why these pills are ineffective for many men who take them hoping for a magic jack-in-the box effect.

As you might suspect, because your sexuality is so intimately tied to your mind, anxiety, defensiveness, fear, and failure of communication are all destructive psychological forces that can take a heavy toll on your libido, whether you’re a man or a woman. They are road blocks to desire. So handle them.

According to Professor Gert Holstege of the University of Groningen in the Nederlands, “Fear and anxiety need to be avoided at all costs if a woman wishes to have an orgasm.”
