Most people know that good blood flow is necessary for a man to become physically aroused, but blood flow is also very important when it comes to a woman’s sexual arousal.

Arousal begins in brain

When stimulated, either physically or mentally, the brain signals the brain to move to certain parts of the body. The nipples become erect, the inner labia swells, and the clitoris becomes engorged and extra-sensitive. The sensitivity is a result of the arteries opening to allow more blood to fill the space, putting pressure on the nerves. The uterus shifts upwards into the body and away from the vagina. The vagina begins to lubricate, then grow to become both longer and wider. Heart rate and blood pressure both increase, causing a “sex flush” on the torso and face.

During orgasm, the muscles will tense and the vaginal muscles will contract. If no further stimulation resumes or continues, the sex organs will return to their original size and position, and breathing and blood pressure will slow back to normal.

What is Female Sexual Arousal Disorder (FSAD)

Some women are unable to achieve arousal. This is called Female Sexual Arousal Disorder (FSAD). The disorder can occur within any part of the arousal process, beginning in the ability to want to have sex, including the ability to be physically aroused or to produce lubrication, and/or the ability to achieve orgasm.

There are many possible causes for FSAD

FSAD can be caused physically, psychologically, or a combination of both factors.

Psychologically-speaking, a woman may be unable to experience arousal or enjoy sex if her mind is not receptive to it. Anxiety, fatigue and stress can all cause sexual disinterest. Relationship troubles can also impact a woman’s sex life, as can emotional trauma, such as a history of sexual abuse or violence, even when with a loving partner.

Another common psychological factors involve poor body image or difficulty adjusting to bodily changes, such as a hysterectomy or a mastectomy. In more extreme cases, a psychological reluctance of have sex can result in vaginimus, an involuntary contracting of the vaginal muscles when confronted with intercourse. The contractions make penetration difficult or even impossible.

The most common cause of FSAD is menopause. The CDC reports that a common symptom of menopause is vaginal dryness and that sex is often painful.

Physically, a woman may decline from sex if it is often painful. This can happen if there is not enough lubrication to comfortably facilitate the friction of intercourse, or if there is some medical complication. Vaginitis is a common cause for pain during intercourse. Meaning simply an inflammation of the vagina, vaginitis is often the result of an infection.

Having an understanding partner who is willing to take the time to learn about his partner is helpful.

Oftentimes, in the case of a psychological cause, therapy can help a woman talk through and conquer her fears or doubts about her sexuality and begin or resume a satisfying romantic life.

Certain blends of herbal ingredients can also help.
