Hi doctor , my height is 173cm , age 28 and weight -68kg. I used to masterburate weekly. But from last week , I am not able to achieve an erection whenever I am trying for it. I usually have acidity problems . From last week , I am having gas problems in stomach . Is erectile dysfunction a result of stomach problems ? I am feeling like I will get too much tired after masterburation .I am very much worried about it. Last week I had a tension regarding my work and I tensed a lot .can it be due to tension ?
