please help πŸ™πŸ½πŸ˜

I need help so me and my boyfriend have been together for quite sometime now and we have done things including oral but he's never really eaten me out and I don't think he likes doing it but that feeling is just to die for so idk what to do. I am very clean and nothing is wrong on my part down there. So any advice on what to do or how to approach this topic to him?!?!!
