Stress and fatigue

It may be difficult to engage in sexual activity when unresolved conflicts persist. Any negative feelings toward your partner may be incompatible with the prospect of sexual intimacy which decreases your level of arousal.

Perhaps the leading cause of lost sexual desire is stress and fatigue. Most often, the condition is temporary and returns when the stressful period ends, or the person is able to get appropriate rest.
Stress compounds relationship issues as one partner is not able to devote an appropriate amount of energy to their partner. Couples need to take make time to spend in a relatively stress-free environment. Take a romantic vacation or perhaps just send the kids to your parents house for the night. If you're looking for something to enjoy with your lover, the Kama Sutra Massage Therapy Kit is a wonderful item. It contains all the items you'll need to massage the stress away. In today's hectic lifestyle, often couples don't spend enough time relaxing together. Start with one evening together. You'll be surprised at how your libido comes racing back.
Sex can arouse a lot of anxiety in some people who are unsure of themselves or fear humiliation. For someone who has never had sex or has had a bad experience with sex, the anxiety level can be overwhelming. One may fear that they will not be able to become aroused or excited and fail their partner. Alternatively, one might fear the consequences of sexual activity (pregnancy or STDs). Fear of the sexual situation because of failure or negative consequences can decrease their interest in sexual activity.
