Everyone is different. It was not something she tried to achieve, but it happened shortly after we met.
She never really squirted, though, until we found a couple of positions that really work for us: female superior or reverse cowgirl. In either position, she will hover over me while I power fuck her from below. This almost always get her to squirt.
She squirts occasionally in doggy style (something about the angle) and a few times in missionary.
For her, it’s definitely a G spot thing and not clitoral. She can achieve it using a g spot vibrator. it’s less of a squirt and more like a gush of fluid.
I think squirting, not necessarily gushing, is a combination of stimulating something that feels really good and also letting yourself mentally accept that what is feeling good is OK and not to be judged. Women are beautiful creatures who are all in there head sometimes and I think getting out of your own way can be a contributing factor for releasing the beast. (please, I am not saying all women here, but just a generalization, so no hate mail) My wife of almost 30 years never squirted until the last few years, and stimulating her manually and slipping a finger in her back door, hit the reset button and now, bingo, she squirts almost every time I do this. I also reassured her that I found this to be a huge turn on for me. PS. you might want to put down a waterproof mattress pad.
one of the main things i have found that helps a woman squirt is placing a firm pillow under their hips and getting the pelvis to tilt just right so the “G” spot and the paraureethral glands are stimulated perfectly.
