i'd highly recommend getting in touch with your doctor if you are having issues with ED, i am in a similar boat, i thought it was low testosterone, didn't think a 36 year old would suffer from ED. i got bloods take and testosterone levels came back fine, was getting tablets from docs with little impact, got sent to urologist and was getting treatment which worked a few times but was painful, i did have a follow up appointment in august but i had recently had back surgery and was on a lot of pain killers and couldnt make the appointment, i wish i had gone as to be honest things have kind of gone downhill since, i'm booked back into the docs for friday again and will ask for a referral back to the hospital, it's not a nice thing to be dealing with
