Hi Beezwax, the thing is are you happy to pay that? I have had ED and now in recovery, its all herbs and a hormone, did all my own reseach and its all pritty healthy, did they do a blood test on him for his testosterone, and other things that arte sex killers, being over weight, stress, anxiety, any meds he could be taken as some are erection killers, alcohol, being a heavy smoker, low labido, I think thats about it, ring any bells.
I will email you a post I have out its titaled DRUGS VERSUS HERBS, HERBS MY CHOICE, please just give it a good read and understand it, you can google anything on there for more info just add for ED on the end, but please give it a 12 week trial and if its working he should see some improvment after 6 weeks, if he starts getting his nocternal erections back and his morning woods then its working, and its a very cheap way to go, one shot will set him up for 3 months, and you wont have to weight for sex as he will be there.
Good Luck
