Q. I don’t have any physical erectile dysfunction problems but…

…I’m aware of psychological ED. Because of this, I like to use Viagra before each training session. Is this OK?

Big Al: In that case, you should do your best to train without Viagra. Your dependence without having a genuine physical issue not only turns your Viagra use into a crutch- thereby not forcing you to resolve the situation on a deeper level- but Viagra has attenuation effects. What this means is you’ll need more of it over time in order to get the same reaction.

You really should only Viagra as needed and as recommended by your physician.

Q. About ”The Squeeze” exercise…

…Where on the shaft does the girth get ”isolated” the most? Because I am really after middle and upper/glans girth.

Big Al: When performed properly the Squeeze should target every aspect of girth. The common missed points are the glans and the base. To make sure you work as much of the base as you can, be sure to dig your hand at the base as deep into it as it will go within the limits of your comfort. For the glans, be sure to have some blood in the glans when you clamp the hand behind it. There should be as much blood in the glans as the rest of the penis.
