Hello, As per your history, it may be due to performance anxiety.  For that kindly avoid stress, overexertion. Take proper sleep of 6 hours. The foreplay will also help. Discuss issues with your partner.  Still, you can take tablet sildenafil one hour before the sexual activity. Keep your self HY Chat Doctor.  Hope I have answered your query. Let me know if I can assist you further.
