What tips can I give my BF about oral?

Hey ladies 💕 so me and my bf we’re both virgins and we were both each other’s first and so we’re not so sure how he can do oral and make it good for me? He always wants to go down on me but I get insecure and don’t let him and finally I’ve let him try it but i didn’t really feel anything 😅 like i guess he wasn’t doing it in the right spot? He’s never watched porn and would be really really against watching it so that’s out of the question 😆 but yeah any tips on what I can tell him to make it more enjoyable for me? Thank you!!!
