Talk to Urologist on Erection & Timing

AoA, I had started masturbating from the age of 15/16years to 34 years... Since then the masturbating timing got short and reached less then 10 secs... Then i got married firstly erection didn't occurred then used some majoon it had worked and everything did right... After that normal erection comes without using any thing... After some months erection dysfunction occurs automatically when i go to intercourse and it didn't work again... My timing remains the same only less than 2 mints... What should i do for timing and for normal erection.. Kindly suggest some treatment thans
