Damn, mine can never make up it's mind what size it wants to be. It seems to react to both physical and mental stress. When I finish my workouts the damn thing shrivels up and looks like a small stack of dimes. This makes for some embarrasing gym showers. I've measured it at 2 inches while it's in "scared turtle" mode. When I'm drunk and relaxed, it hangs a modest 3.5 inches soft. I also tend to have different sized erections. Sometimes only the shaft gets hard making for a small, slightly under 5 inch erection. However, if I'm turned on real good, the head swells up along with the shaft and puts me at a normal 5. 5 incher. Does anyone else have so much variation in their size?
