I don’t know how to tell my boyfriend I’ve been faking it and want sex

So be and my boyfriend haven’t been official for very long but we have been a thing for over a year. We have only ever had sex once. We always end up either using our hands or oral we have even used my vibrator. But… tbh it’s never been enough to make me cum. I always just go with yes I did because I don’t want to make him feel bad or like he’s not good enough. I’m one of the few girls that comes faster with penetration. I really just want to have sec with him but his ex used that against him all the time so I think that might have something to do with it. I just don’t know how to tell him. Someone please help
