Hello thanks for asking from HCM for your health related queries I can understand your concern. The symptoms you are showing like inability to sustain erection could be occurring most likely due to erectile dysfunction. As you are able to get erection but it is not being sustained so most likely the cause for your loss of erection is psychological, still medical causes like diabetes or hypertension should be ruled out first. In erectile dysfunction proper reassurance and increased duration of foreplay helps in sustaining erection. Try to spend more and more time in foreplay and don t think about not getting erections. The anticipatory anxiety about poor erection further worsens the erection so try not to think about this again and again. Medicines like PDE-5 Inhibitors as Sildenafil, Tadalafil etc are very useful in erectile dysfunction. These medicines are usually advised to be taken about half to one hour before intercourse and result in improvement of erection. You can consult a psychiatrist for your problem and take prescription of these medicines. Don t remain frustrated such symptoms can be treated with proper medicines. Thanks, Hope this helps you. Take care. Dr. Seikhoo Bishnoi MD Psychiatry
