Why not try cutting back on the Saw Palmetto and the Horny Goad and see if it's better.

Getting an erection only helps part of the problem, the rest of the body may not be fit enough, I suggerst you give him a helping hand if you know what I mean.
I am 64 and have no erection problems, I do take Atenolol BP tablets, I find when making love to my Wife I sweat like a waterfall but cannot come to an orgasm, she gives me a helping hand afterwards, I like to make sure she has an orgasm first, there is more than one way to skin a rabbit.
