Sexual arousal disorders affect women and men. With this disorder men find it difficult to obtain or keep an erection while women there is the inability to lubricate enough to complete the sex act. Sexual arousal disorders were previously known as frigidity in women and impotence in men, though these have now been replaced with less judgmental terms. Impotence is now known as erectile dysfunction, and frigidity is now described as any of several specific problems with desire, arousal, or anxiety.
Women may encounter persistent difficulties becoming sexually excited or sufficiently lubricated in response to sexual stimulation. This dysfunction can occur after a woman has been functioning normally over the years. Oral sex and masturbation are the only times when women with this dysfunction can become lubricated. Some women find vaginal lubrication easier or existent with one partner over the other. This can lead to other sexual dysfunctions in women such as hypoactive sexual desire disorder and orgasmic disorders. Erectile dysfunction is characterized by the regular or repeated inability to obtain or maintain an erection. Analyzing erectile dysfunction allows you to decipher the causes. Obtaining full erections at some times, such as when asleep (when the mind and psychological issues, if any, are less present), tends to suggest the physical structures are functionally working. Psychological and physical factors contribute to this dysfunction which include stress, levels of fatigue, gender identity, health, and other individual attributes and experiences.
