Hi ive been a patient of urologists before and had a question on what to do. Ive gone last summer for erectile disfunction. Im 24 yrs old and cant seem to get an erection or if i do rarely it stays for only a few seconds. They said it may be psychological. Im having my doubts though. Cialis 20gm will allow me to have sex however i cant afford or want to keep taking pills forever especially this young. Im unsure of what to do. My testosterone levels and cholesterol levels are normal. I eat healthy exercise and drink lots of water. I never get erections during the day or mornings like most men though if that helps any. Please if theres anything you can do for me i would greatly appreciate it!
