There are many methods of enlarging and lengthening the labia and the clitoris. Many people do so. You might want to check out a website www.o-pearl.com for a view of a woman who has used piercing, weights, and stretching for years in order to see what she has been able to accomplish. She takes it to an extreme, of course, but even just pulling on your lips while you watch TV will, over time, stretch them out. Piercing is the method which I use with my pets, as I find it very attractive. Naturally, only a qualified piercer should be used for such important proceedures. You mention a vacuum, there is also a method of inserting saline through a needle. I'm sure there is a lot of information on all of these methods on the net. Good luck to you. Let us know how it all works out, and what methods you decide to try out.
