I'm sorry. But, I have to say this is a pen driven issue.

Most women Can't/don't squirt.

Ever wonder why is the same few women in squirt vids? Because only a few can do it from pleasure and even then it's mostly contrived/for show.

Also, squirt is essentially a woman pissing while having and orgasm or feeling intense pleasure. Nothing more.

Most women cum by just a full clenching of the vagina, staggered breathing and a flow of wetness. But, projectile liquid is very rare and again, it's pee.

Is it hot? Yeah.

Is it abnormal that your gf doesn't squirt? Absolutely not.

Some women have harder time racing orgasm than others. And sometimes you just need to experiment enough to find out what scratches the itch and not blame each other for it.

A female orgasm is exceedingly mental and at this point she's probably thinking way too much about cumming so she just can't. It's a catch 22.

Keep trying new things. Techniques, positions, whatever... with the full understanding that if she or you don't cum it's perfectly ok.

This alleviates stress and makes everything more comfortable so you can try new things and hopefully get her to that point.

Understand you may not. Try to pleasure her, but by all means don't make cumming for the goal for either of you.

Also, ask her what she likes. Tell her you want to know what she likes and when she finds a few things, you'll get into a rhythm. Communication is key.

But, thinking she has to squirt to be fulfilled is unrealistic and harmful to both of your enjoyment.

Talk to her. Be adventurous and try new things. Tell her to communicate. But... please please have reasonable expectations and enjoy the things type doing to rapture instead of paying some pen driven fantasy.
