Some women who want to become men undergo hormonal therapy which causes their clits to enlarge. So they don't so much have a penis as they have a gigantic clit
Imagine that wiggling in your face! They are also usually only 2 inches or so ;o
OR THERES THE OTHER OPTION WHICH IS BASICALLY PUTTING FAT FROM YOUR ASS ONTO YOUR CLIT SO YOU CAN HAVE A CHUBBY.
