SO can’t make me orgasm

So my boyfriend is very giving when it comes to trying to make me orgasm, he goes down on me for as long as I️ want and fingers me but I️ can never orgasm! By myself it takes me less then 10 minutes. We have been dating for a little over a month, I️ am very comfortable with him but it’s starting to get really frustrating. I️ go down on him and he comes every time so I end up feeling left out and bitter. Is anyone else having this problem with their S/O ?? Any suggestions???
