I've been tattooed over my spine and ribs, pierced my own nose and ears, broken countless fingers etc, and let me tell you that getting my chest waxed was hands down the most painful experience I've ever had to go through. I've had my back waxed dozens of times and that feels like a blowjob compared to getting my chest waxed. I will never EVER do that again.
That's good to know. I have my back waxed about every 3-4 months for the last 5 years or so. Never done the chest, but I considered it. I think I'll unconsider it now...just pulling the odd stray hair from my chest is tear-inducing sometimes, so I can imagine going the full monty must be hell.
