I don't know how to eat a girl out

So I recently just got into this relationship with a girl. This is my first girlfriend & I've given head to guys before but never a girl. I know that sex will probably be apart if our relationship cause we talk about it, but I don't know how to eat a girl out. & I'm kind of embarrassed to tell her or ask anything about it to her. Any tips?

Every person is different. Your communication with her should be open enough that you should be able to ask her what she likes... then do that.
