How to cause the female ejaculation
There are a few things to consider. Squirting isn't always a guarantee. It's always best to pee before sex and ensure she is completely relaxed.
Squirting is caused when the Skene's gland, a small gland located near the G-Spot, is stimulated and releases the fluid its holding.
The fluid is a watery prostate-like fluid.
You can't actually feel the Skene's gland but if you can find the G-Spot, the gland is within the area.
1. Ensure repeated stimulation
Clitoral, skin, vaginal and G-Spot stimulation should be done as much as possible. The Skene's gland is more likely to ejaculate when she is highly stimulated.
2. Repeated thudding
This can be done with a toy especially, provide deep repetitive pressure below the surface of the vaginal wall.
Tension will build up and the resulting feeling will almost feel like an urge to pee. If you have already relieved yourself then you won't have anything to worry about.
It will be part of the signs that she's about to climax and as stimulation continues, she will eventually squirt- or not. But you'll both have fun trying.
