A woman can also get a genital piercing that would increase sexual pleasure. One on the lip of the vagina and would be called the labia. There are a variety of places in our body where you can get pierced. Basically, you can pierce anything that has loose skin. You can also stretch piercing holes.
Hole stretching causes a fairly large hole, some as big as dime, with a gauge inside.
You can start off with something small, like a 16 gauge and gradually step up size by size. An alternative is to do it all at once. Ten gauge and up are more painful and can take a little longer to heal. Usually a piercing doesn't hurt too much. A needle is very sharp so it goes through the skin easier than a piercing gun.
