Hi Loren,
The situation you describe is not too uncommon especially in those of us who are over 50 or so.
As you may know, erections occur, when a man is sexually aroused, due to blood flowing into the penis thru arteries and being held there by constriction of the veins. Erectile dysfunction is a condition whereby the arteries never relax to allow the blood to flow into the penis. Once the condition is treated correctly the blood flows in and the penis becomes erect.
All erectile dysfunction medicine such as Viagra, Cialis, Levitra, and their generic equivalents (i.e. generic viagra, or sildenafil citrate, etc) treat the problem in the same way: by relaxing the muscles surrounding the arteries in the penis to allow normal and enhanced blood flow into the penis.
These medications normally do this quite well but often with side effects and many men such as yourself do look for safer alternatives.
I know of two that work quite well, and the customer care department is exceptional. Besides those things, which I beleive are the most important, the delivery is quick and the prices are quite good.
I would suggest that you check out these two products to see if they will be a solution to your situation.
http://www.maxerectionhelp.com/ and
http://www.fasterectionhelp.com/ - the main difference between them is the length of time the effects stay active. One works for about 4 hours and the other for 24 to 36 hours. Neither one "makes you get an erection", that is, like Viagra and Cialis they work when you become sexually arroused.
Good luck.
