Squirting Question

Okay so, my boyfriend and I have been doing IT for months now. I have always wanted to squirt, but can’t. I’ve came before, the white stuff, but not squirted straight up liquid. I also have used a vibrator, but the build up is too powerful, I always have to stop using it. What do I do? I’ve been masturbating for like 2-3 years and can’t bring myself to it.
