Public exposure, so to speak, is always delicate (I’m not talking about Weiner and his magic tallywhacker here) but, face it, someone has to do it. And J.D. over at the Mouth of the Brazos has come mighty close:
“If these products are so great, I will buy any or all of them, on the condition that they show on screen a wore-out, obese, old fart with diabetes and high blood pressure and heart disease with a rock-hard phallus ramming it into one of those chicks.”
Allow me to, as it were, go all the way there: In my experience, having reached the Psalmist’s three score and ten, Viagra and its clones are a scam. All I got from the big V was a headache and dizziness. Much more likely to work are 1) going on a low-to-zero carb diet, 2) quitting smoking and 3) exercising daily. Not that I really care to try two or three.
THE TEXAS SCRIBBLER 
I suspect that these products are aimed at the youngsters, as most entertainment products are.
Sad but probably true. As J.D. points out, the rumors of six-hour erections are fables. Even my doctor shot that one down before handing over the prescription.
