Im a 30 year old female and have noticed my libido is decreasing. i dont take meds, not on birth control and i am definitely attracted to, love and desire my partner. i think about being intimate, but its at random and only brief. im always tired?

If you are always tired and you are getting enough good sleep, then you should be tested for such things as anemia, diabetes and thyroid problems by your doctor. At 30 your life is way more complicated than when you were younger with job and life responsibilities that are different. This can affect your libido a lot.

Please have a complete physical exam to see if you have an illness or deficiency. If it is not physical, see a Clinical Psychologist with expertise in multiple types of psychotherapy to evaluate your problems and help you. If you need medication managed by a Psychiatrist in addition to psychotherapy your Psychologist can help you figure that out.
