Physical causes of painful intercourse differ, depending on whether the pain occurs at entry or with deep thrusting. Emotional factors might be associated with many types of painful intercourse.

A) Entry pain: Pain during penetration might be associated with a range of factors, including:

1. Not enough lubrication. This is often the result of not enough foreplay. A drop in estrogen levels after menopause or childbirth or during breastfeeding also can be a cause.

2. Certain medications are known to affect sexual desire or arousal, which can decrease lubrication and make sex painful. These include antidepressants, high blood pressure medications, sedatives, antihistamines, and certain birth control pills.

3. Injury, trauma, or irritation. This includes injury or irritation from an accident, pelvic surgery, female circumcision, or a cut made during childbirth to enlarge the birth canal (episiotomy).

4. Inflammation, infection, or skin disorder. An infection in your genital area or urinary tract can cause painful intercourse. Eczema or other skin problems in your genital area also can be a problem.

5. Vaginismus. These involuntary spasms of the muscles of the vaginal wall can make penetration painful.

6. A problem present at birth. Not having a fully formed vagina (vaginal agenesis) or the development of a membrane that blocks the vaginal opening (imperforate hymen) could cause dyspareunia.

B) Deep pain: Deep pain usually occurs with deep penetration. It might be worse in certain positions. Causes include:

1. Certain illnesses and conditions. The list includes endometriosis, pelvic inflammatory disease, uterine prolapse, retroverted uterus, uterine fibroids, cystitis, irritable bowel syndrome, pelvic floor dysfunction, adenomyosis, hemorrhoids, and ovarian cysts.

2. Surgeries or medical treatments. Scarring from pelvic surgery, including hysterectomy, can cause painful intercourse. Medical treatments for cancer, such as radiation and chemotherapy, can cause changes that make sex painful.

C) Emotional factors: Emotions are deeply intertwined with sexual activity, so they might play a role in sexual pain. Emotional factors include:

1. Psychological issues. Anxiety, depression, concerns about your physical appearance, fear of intimacy, or relationship problems can contribute to a low level of arousal and resulting discomfort or pain.

2. Stress. Your pelvic floor muscles tend to tighten in response to stress in your life. This can contribute to pain during intercourse.

3. History of sexual abuse. Not everyone with dyspareunia has a history of sexual abuse, but if you have been abused, it can play a role.

4. It can be difficult to tell whether emotional factors are associated with dyspareunia. Initial pain can lead to fear of recurring pain, making it difficult to relax, which can lead to more pain. You might start avoiding sex if you associate it with pain.
