Viagra is marketed for guys that need help... but... It was actually some young (28ish) rock climbers that turned me on to what they called "Recreational Viagra". Most Viagra comes in 100mg tablets. Get a pill splitter and quarter it, that's all you'll need, and enjoy... just make sure the victim... err... I mean girlfriend is planning on hanging around for a couple hours and doesn't mind walking bow legged the next day... LMAO
