Where is the clitoris?

1) Hi Alice,

I have a stupid question. Where is the clitoris located exactly in the female's genitalia? If it differs per woman, what is the easiest way to locate it?

Thanks,
Can't find

2) Dear Alice,

I really don't know where the clitoris is. I have tried many times to touch my girlfriend's clitoris, but she can't feel anything. Of course, she can't get any feeling from intercourse. What can I do now?
