Should I tell him the truth?

Stella

So I've been lying to my boyfriend since we had sex for the first time. We've been dating for a year and I fake an orgasm every time we have sex. I've never had an orgasm with him and now I feel like I'm in too deep to tell him the truth, I know it would hurt him deeply and I don't know what to do. I feel awful but I dont want to hurt his confidence. The sex is still great but I just cant cum with him. I know I fucked up by faking for so long and I dont know what to do now.
