Libido

Nocturnal penile tumescence (abbreviated as NPT), also known colloquially as “morning wood”, is a spontaneous erection of the penis during sleep or when waking up. All men without physiological erectile dysfunction experience nocturnal penile tumescence, usually three to five times during the night, typically during REM sleep. NPTs are believed to contribute to penile health

If you have little or no interest in sex for a long time and take initiatives in making love or if you avoid or refuse sexual situations, it is possible that you have a disorder with a reduced interest in making love.

If you don’t have sexual fantasies, exiting thoughts about sex or you look at yourself as not being sexual, you may have this disorder. In short, you don’t have sexual thoughts, fantasies or dreams and you don’t take initiatives in sexual activity.

Erectile dysfunction (ED), also known as impotence, is a type of sexual dysfunction characterized by the inability to develop or maintain an erection of the penis during sexual activity in humans. A penile erection is the hydraulic effect of blood entering and being retained in sponge-like bodies within the penis. The process is most often initiated as a result of sexual arousal, when signals are transmitted from the brain to nerves in the penis. The most important organic causes of impotence are cardiovascular disease and diabetes, neurological problems (for example, trauma from prostatectomy surgery), hormonal insufficiencies (hypogonadism) and drug side effects.

Psychological impotence is where erection or penetration fails due to thoughts or feelings (psychological reasons) rather than physical impossibility; this is somewhat less frequent but can often be helped. Notably, in psychological impotence, there is a strong response to placebo treatment. Erectile dysfunction can have severe psychological consequences as it can be tied to relationship difficulties and masculine self-image.
