> I have a huge labia and clitoris
Different people have different ideas as to what constitutes "huge". Labia can vary from pretty well non-existent to enormous flaps of flesh. A clitoris can vary from all- but-invisible to a couple of inches long and still be quite normal. If it's over two inches, then it might indeed by termed huge.
> and they seem to be getting bigger.
Possibly in the absence of estrogen the clitoris might enlarge, though it's unlikely the labia would.

I was thinking more about a testosterone patch, rather than cream -- rubbing testosterone cream on the clitoris would almost certainly make it grow. That's not actually a bad thing at all -- the bigger it is, the more sensitive and the more a focus of feeling it becomes and I think most men prefer a woman to have a large clitoris, but some women feel that it may be a bit masculine. A larger clitoris may be easier to stimulate and stimulation is always helpful in sex.
