Squirting?

Any tips on how to pass the mental block and squirt during sex? I’ve heard that is feels like peeing so that you have let yourself relax and “try to pee” to squirt. If that’s the case then I have to pass this big mental block and I’m not sure what to do. Do I have this conception incorrectly or no? During sex, it feels like I’d need to pee and sometimes it builds up to the point it gets painful to hold it in. I’m not sure if me releasing would be squirting or if this is something else. Any tips if this is the case though?
