Help! Can’t orgasm!

So me and my partner have been doing the deed for about two years now and he has never gotten me to orgasm. I have been close a number of time but I think he has given up trying to help me finish because I have never been able to with him. I occasionally orgasm by myself but when I tell him that, he gets even more undetermined because it seems to be a problem with him and not me…. I feel bad because I want him to be confident and I want him to be able to help me finish but I can’t make it happen and he seems to have given up helping me. I need advice!!!!
