Hello, You are experiencing severe pain per vagina when your partners tries to have penetrative sex. You are suggested to stay relaxed during foreplay and sex. Let your vaginal and pelvic muscles relax. If you are in anxiety and stress, your vaginal and pelvic muscles tighten causing penetration difficult. Get mentally and emotionally ready for foreplay and sex. Let the foreplay be long so that lubrication is best. Good lubrication helps penetration. Since you are a virgin, you should get clinically examined by an OBGYN. Get per vaginal examination done to detect if you have imperforate hymen, septate hymen, micro-perforate hymen, etc. In case the vagina is covered with a thin extra band of tissue or completely covered with skin, your treating OBGYN may have to do minor surgery to fix the cause. It will take a couple of days to heal, you will be given antibiotics to prevent infection and for quicker healing. Take care of your hygiene. Stay away from addictions if any. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Nupur K., General & Family Physician
