How to get my girlfriend to listen tl me?

My gf wants me to go down on her but her vag is a forest and doesn't snell the best - how can I get her to either shave or not ask me to go down on her -- I asked het before and she said she doesn't beluev in shaving as it's Un natural-- and don't give me this "don't ask for a bf" thing either that's just dumb
