The "Pinocchio" Curse: NSFW Edition

Someone you upset hits you with a botched black magic spell. They wanted to give you the classic Pinocchio curse where your nose grows when you lie, but the spell glitched. Now, instead of your nose growing, it happens to your penis.

The Rules:

• Growth: Every time you tell a lie, it grows half an inch. If you do not have a penis, one starts growing from scratch.
• The State: It stays fully erect all day long.
• The Inversion: If you actually get horny, it immediately goes flaccid. This stays in effect as long as you are even a fraction of an inch above your original starting size.
• The Reversal: To undo the growth from one lie, you have to admit that lie to the person you told it to, and then confess one extra lie from your past to them.
• The Return to Normal: You only get your normal function back (arousal working the way it should) once you have confessed enough lies to shrink back down to your exact original baseline.

How badly does this mess up your life? Do you think you could actually adapt to being 100% honest and confessing your past to everyone, or would this situation just spiral out of control within a week?
