Hello dear I understand your concern I think you have sexual anxiety that cause erectile dysfunction. Other cause are fatigue, stress, relationship issues, diabetes, obesity. Take following advice Start exercising, like walkigna nd yoga, pelvic exercise like kegel exercise Do discussion with your partner that help in gaining psychological trust Distract your mind from sexual stimulation, withdrawing the penis altogether, purposefully ejaculating before sexual intercourse Use more than one condom and try womrn in top position, use squeez technique to reduce excessive arousal If problem persists then take tablet sildenafil plus paroxetine 30-40 min before sex after proper evaluation by urologist Hope this may help you. Take care Best regards Dr. Sagar
