Imagine for a moment, if you will, an unexplored circle of hell wherein it is indistinguishable from this mortal plane ..
except..
You can only become aroused by the sight of your OWN flacid penis. But NEVA your own erect penis.
The torture is as follows:
1.You see your own flacid penis, and so you become aroused.
2.Due to that arousal, your penis becomes erect..
eeeeyuck! That's not your thing!
3. Instantly you're turned off, and your erection relents and dwindles.
4. Rinse and repeat.
