Squirting

How do you squirt? I’ve tried everything I know some people can’t but I get the urge every time but I can’t get over peeing during floor play. I understand it’s not peeing lol, but any other tips? We’ve tried going down on me, fingering me, toys, I tell him when I have the urge. I just feel like I can’t satisfy him because he wants me to do it so badly but he understands I’m having a hard time with it.

Any advice helps
