Okay, so this is totally embarrassing, but I am curious.

I am 16 years old, and I have a problem. I have an enlarged clitoris of maybe 1/2 an inch to an inch. Is this normal? It has been here as long as I can remember and is a very embarrassing thing.

Also, is it normal to grow a little more than usual hair on your stomach below the belly button? And how do I reduce bumps where I shave down there?

As for hair growing below your bellybutton, not unusual. Before I had my son I had a fine line of hair growing from my button down to my pubes; that disappeared shortly after he was born. It is normal. I stopped shaving when I discovered that a depilatory did the job quicker and without bumps. Use Neat, or something similar. It does a good job.

Clitoral sizes vary same as penis sizes.
