Pain during intercourse severe enough to prevent penetration can happen for several reasons, and this is a common problem that can usually be treated with proper evaluation and support. Possible causes include vaginal dryness, fear or anxiety related to intercourse, tightening of vaginal muscles due to stress or pain anticipation, infection, inflammation, hormonal issues, or rarely structural problems. When intercourse becomes painful repeatedly, anxiety and fear may increase further, making the muscles tighten automatically and causing more discomfort. Since you have been married for 6 months and intercourse is still not successful, it would be important to consult a gynaecologist for a proper examination and guidance rather than continuing to struggle in pain. Try not to force intercourse, as this can increase pain, fear, and muscle tightening. Spending more time on relaxation, emotional comfort, and foreplay may help reduce anxiety and improve natural lubrication. A water-based lubricant may also help if dryness is contributing to the pain. Open communication with your partner, reducing stress, and taking things slowly can make a big difference. Depending on the cause, treatment may include treating infection, relaxation exercises, counselling, pelvic floor therapy, or other medical treatment advised by the doctor. Since you are planning a pregnancy, getting a proper evaluation early is a good idea so that both pain and conception concerns can be addressed safely. Seek medical attention promptly if you also have fever, abnormal discharge, bleeding, severe pelvic pain, or burning sensation.
