There’s lots of topics on squirting on here so have a search and you’ll find plenty to read.
Generally though, the best advice I can give is not to put too much pressure on yourself. Going in with the attitude of “I’m trying to squirt” will almost guarantee that you won’t. There are various techniques that you can use, all ultimately involved being relaxed, comfortable and enjoying yourself, so only do those that will be pleasurable for you.
We actually don’t know if all women can squirt (be that be able to make the fluid at all or expel it from their bodies). Often once someone has done it a couple of times, it becomes much easier to do regularly.
Most of what we know about squirting (how to and what it is etc) comes from people sharing their experiences rather than scientific study.
When people talking of “squirting”, sometimes they mean actual squirting other times they mean gushing, sometimes they don’t know there is a difference. Essentially:
Squirting is a clear liquid that comes out the urethra. You can squirt with or without an orgasm. Clitoral or g spot stimulation (or both) can work for this.
Gushing is a milky coloured liquid that comes from inside the vagina. You need to orgasm do this and generally g spot stimulation is the best way to go.
Neither is necessarily better than the other. Also just because some squirts/gushes, it doesn’t mean the orgasm is better.
