I need help cumming ):

My boyfriend have been together for almost 8 months. We've had sex so much but there's a problem! I don't feel anything. I fake it every single time. Like, I feel the pressure of his dick going in and out of me, but I don't feel any pleasure. Sometimes when he rubs my clit I feel a lil something but it's never enough that I cum. I have never came in my life. I've only been with two people. My ex and him. But my ex just used to finger me and give me head and I NEVER CAME THEN. And with this one, we've done everything. BUT I HAVE NEVER CAME. Just him. Believe me, I'm always aroused and super wet. But it just always stays that way. At this point I get pleasured if he's pleasured lol. Btw I have never told him this and I don't want him to think it's his fault. Is it mine? Is it my body? Please help or give me tips!
