Lots of young guys on this thread
I am at 21 months. There may be some slight improvement going on, but no suitable erections on just Viagra or Levitra (or Cialis). I do generally take a full dose of either generic Viagra (100 mg) or generic Levitra (20 mg) daily, and can get semi-erect with that.
Thank God for injections. Great results with the bi-mix that I'm using now, so my "batting average" is going up. I do notice on days right after the injection I can get more firmness than on days further from injections. I am now trying to do injections every 3 days or so, whether I have sex or not, just to get the feeling of swinging the old bat back.
