Female sexual arousal disorder (FSAD) is a condition in which the individual's body does not respond to sexual stimulation. It is a sexual dysfunction that is very common but treatable. Some symptoms of FSAD include low sexual desire or libido, lack of sexual thoughts, decreased sexual excitement, reduced arousal from internal or external stimulation, and lack of sensation in the genitalia or other arousal parts of the body.
There are various causes - both physical and psychological - that can affect sexual desire or libido. Some include mental health conditions such as anxiety and depression, increased stress, insecurities, and low-self esteem, physical/sexual abuse, hormonal conditions, medication side effects, etc.
Alcohol has the ability to interfere with sexual stimulation by disrupting the signals sent between the brain and the genitals. It is common for those with alcoholism to experience low sexual desire, disruption in arousal (lubrication in women, and erection in men), and ejaculation disorders (such as delayed ejaculation).
