That's crazy. I would never suggest cutting into yourself at home. Maybe if you are a doctor and know what you are doing. Maybe. But otherwise, absolutely not.
If you are underage and do not want to talk to your parents about it, you should probably wait until you are old enough to have it done all on your own.
Other than that, all that I can tell you is that as a woman, I honestly cannot imagine that bothering me in a lover, so don't do it just to impress anyone.
