Help Wanted/Absolutely Needed

So I need some help from my fellow girls. My boyfriend and I have been together for awhile and I have been having some trouble in the bedroom. He says I'm amazing with everything I do for him from the head to the hands. But when he goes to return the favor, I get nothing. Don't get me wrong it feels good, but I just don't orgasm. Sad to say, I never have with him. I tried coaching him and telling him where it feels good, yet I just don't know what to do anymore. Any help is welcome and needed!
