Squirting help!

So my boyfriend and I have been trying these past couple times to get me to squirt and I'm having difficulty with it. I've never been able to do it on my own and he's able to reach my G spot and I try pushing like I've read but nothing happens. I'm perfectly content if it's just not possible, but it never hurts to try and I know some women who can get there likes it's nothing 😂 I don't know if I'm not relaxed enough or what but I would really appreciate some advice and/tips!
