I've heard about the injection story into the penis and I didn't believe it then. Is this still the common method used though? Thats insane if the guys do that!

With Viagra out their, I would guess guys would try that if they can get it. I've tried to get some myself but unsuccessful. Anyway...

I've always wondered about this, other people have told me its all about concentration but thats gotta be BS so How else can these guys stay hard for so long????
