If you'd actually tell a woman about this procedure you're utterly braindead.
1) There is no 'fair is fair'. Here's the reality: society pushes accepting all women's body issues, but not for men. She will totally expect you to accept all HER flaws but will have no interest in accepting yours. Here's where you counter and say she's not the right girl then, but 100% of women are like this, so if you don't accept a girl like this, you'll die alone.
2) Women are incapable of keeping a secret. You tell her, you can guarantee all her friends will know by the end of the day, and if you breakup she'll spread it far and wide to spite you.
3) You have absolutely no advantage to be gained from telling her, yet the downsides are significant. Don't be a cuck, do what's best for yourself. I assure you, women always do.
