Faking it

Been with my hubby 7 yrs now.. I hate to say it but I've never had an orgasm with him. I can get off in like 5 mins by myself. But even doing it myself with him I can't 😧. Don't get me wrong I love having sex with him and frequently start it. It feels good and stuff. I'm super wet. But I just never get the "oh snap, convulsions, twitching head high feeling" I get when I masterbate. N how the hell do I tell him after all this time??
