Not all sexual problems require medical attention. Many people have temporary sexual problems, usually due to medical problems, to anxiety, or to stress in another area of life. If you are distressed by the problem or you are afraid your relationship is threatened, don't be afraid or embarrassed to seek outside help. If your health care provider is unable to help you beyond ruling out physical problems, a mental health counselor should be able to help or point you in the right direction.
Any sexual problem that persists for more than a few weeks is worth a visit to your health care provider. He or she can rule out medical or medication causes of the problem and can offer advice on solving other types of problems. He or she can help you sort out exactly what the problem is if you aren't sure. He or she can refer you to other specialists if necessary: a psychotherapist, a marriage counselor, or a sex therapist.
Your doctor may want to examine your vaginal or urethral discharge under a microscope or test your urine. Trichomoniasis occasionally shows up on Pap tests in women with no symptoms. Your safest course is to get tested if you think you may have been exposed to the parasite.
