Impotence effects more men than you might think.  This condition, also called erectile dysfunction, effects millions of men in the U.S..  Erectile function involves psychological as well as physical arousal, with increased blood fllow to the penis.  It is the continued increased flow that sustains the erection until ejaculation occurs.
 Impotence occurs when there is frequent difficulty with having or sustaining an erection.  In it’s wider definition, impotence means the inability to become sexually aroused and not just erectile dysfunction, but it also does come in many forms such as inability to sustain an erection, inability to get an erection in the first place (impotence) and inability to become sexually aroused, which is many times sufficiently psychological in nature.  Inability to get an orgasm such as what the mutliple orgasm supplement Deer Antler Plus is supposed to help with, is another very unfortunate form of ED. 
 It is believed now, that physical factors have a direct link to erectile dysfunction problems and there is help and treatments available. Erection problems become more likely as men age, but age alone is not the only cause. 

 Male infertility should not be confused with impotence.  This term refers only to the inability to produce a sperm that can fertilize an egg.  Premature ejaculation refers to a male’s orgasm coming on too quickly. This is not considered the same thing as impotence but it can cause problems with intimacy with your partner.  Counseling is recommended for premature ejaculation for the couple and also for natural libido help.
 As a couple, if impotence is a problem, make sure you communicate with one another.  Anxiety about sexual performance should be discussed by both and counseling is helpful.  Unresolved anger and conflict may be expressed by the male holding back on their erection.  Due to the complexity of human sexuality, all the physical and psychological aspects of impotence problems should be addressed when meeting with counselors and physicians.
