This is EMG's classic "Never Fully Flaccid" file with an added binaural. It seemed a bit overpowering at first and I considered mixing it down a little, but after listening all the way through I concluded it was very effective as is. The original description follows -- This file is for men and makes it so that the listener's dick never goes fully soft. Beginning after the next time you get an erection, your dick will stay nice and plump afterward. A decent amount of blood will always stay in your dick, not enough that you're always hard, but just enough that there will always be a nice bulge in your pants. It will feel good to listen and stroke to this file often to reinforce the subconscious regulation of blood-flow to your dick.
