Hi Ged, have you tried herbs, as there are some things that will help open up your viens, I did a post and most things are in it that will help, its how I got out of ED and now in recovery, the post is tital
HERBS VERSUS DRUGS,
HERBS MY CHOICE, all I can ask is you give it a read, then give it a trail, its a very cheap way out of ED if it works for you.
Good Luck
What is below is a reply I put in to a discussion on side effects to ED drugs.
