Need ideas

Whenever my boyfriend goes down on me it doesn’t always feel that good like sometimes it was like that was okay but it’s nothing near being able to get me to climax and I have no clue what to do, I actually find it hard in general for him to get me to orgasm, I’m not really the type to orgasm from penetration i do like it but prefer stimulation on the clit but he’s never really able to get me to climax he has twice and he’s gotten me close a couple times but can never seem to finish, and it’s super irritating!! Any ideas?
