Saita08, You do not say how old you are? Do you have any medical condition like PCOS? PCOS increase the testosterone in your body and can cause an enlargement of your clitoris and hair growth in a masculine pattern.
Have this been like that from the beginning? Does everything else look fine and work ok? Is it very sensitive and can you orgasm from it?
A woman's clitoris is rather large. It goes deep into your body and under your labia for about 6 to 8 inches.
It is probably just what you are saying, a large clitoris glans (head). I can bet you that men will find this very sexy.
Take care!
