Its hard for me to orgasm with my boyfriend

my bf and I have been together since may. he was my first time and we always have really great sex. so good that we do it nearly every day. the problem is that I can really only orgasm if i’m the one doing the work. he eats me out all the time and plays w my clit while we have sex and it feels really good but he’s only made me orgasm 3-5 times in our whole relationship. he tries really hard and I know he gets discouraged too when I can’t orgasm with him. I honestly don’t know what to do anymore and could use any advice on how to help him give me an orgasm.
