What is happening with you is either due to 'Vaginismus' or due to 'Penetration Phobia'. Vaginismus is an involuntary spasm of vagina during penetration, which makes penetration painful and even impossible. Penetration phobia is invariably a psychological phenomenon, which is a result of past trauma, emotional, psychological or even physical; or due to irrational beliefs and incorrect information accepted during vulnerable phases of life in growing years. For the treatment, couple needs to consult a trained sex counsellor in person. There are no medications that can treat this situation. The treatment includes counselling/psychotherapy and sex education.
