How to get him to eat me out?

Savannah • Embracing awkward since '00
Every time I meet with my friend with benefits he is unable to get me to orgasm. He fingers me but I just can't get there. He keeps asking me "what do I need to do differently?" How do I hint to him that I want him to eat me out? I can give myself an orgasm by fingering but he can't, would eating me out help?
