Diabetes mellitus is a condition that may lead to erectile dysfunction. The testosterone levels decrease thereby affecting the performance of the testicles and the pituitary gland. Testosterone is the primary sex hormone that stimulates and promotes sexual characteristics.This condition also causes improper erection and reduced desire of having sex.

Lazy erections that are not even enough to penetrate also signify dysfunction of the hydraulic mechanism of the blood flow through the penis. Such a condition may signify an underlying clinical condition, often cardiovascular in origin, that eventually causes erectile dysfunction.

Premature ejaculation is one of the symptoms that might help in identifying erectile dysfunction. If your intimate session with your partner doesn’t last long and you ejaculate quite ahead of orgasm, then you might be in the first stage of erection dysfunction disorder. 

If it has been months or years since you reached orgasm during intercourse, then you might be suffering form erectile dysfunction. Orgasm needs an erection that is hard enough throughout the sexual intercourse. If you have not achieved it for quite a time then it might be a symptom of erectile dysfunction.

Inability to have a gratifying sexual act with your loved one is also a hint of the inability of your penis to erect completely. In this case as the erection is not stiff, the pleasure of the act for both the partners starts dying away, eventually killing the desire to indulge in such intimate activity.

If you feel that the urge of having sex is gradually subsiding and you are not able to hold erection long enough to complete the intercourse, then there is a serious chance of erection dysfunction. The disinterest is quite obvious as sexual intercourse does not reach the climax.

If there are so-called psychological aspects associated with erection then it might be erectile dysfunction. By psychological aspects we mean having proper erection in morning or while masturbating and during night, while dreaming, or fantasizing, but not under normal conditions.

If the erection can’t be sustained long enough to penetrate or finish sexual intercourse, then it can be a case of erectile dysfunction. If the erection occurs for a small time period, then it might be an indication of some serious malfunction in the mechanism of blood flow through blood vessels present in the penis.

If one feels aroused but can’t achieve proper erection then he is most likely suffering from erectile dysfunction. Even if erection occurs but is not as stiff as it should have been, then it might be an indicator of erectile dysfunction.
