1. Keep yourself very hydrated
2. Empty your bladder beforehand
3. It doesn't happen straight away. It is extensive clitoral and g spot masturbating
4. It varies. Some women can squirt via clit stimulation. Or g spot, or sometimes both
5. Your OH needs to stimulate these areas with plenty of gusto - no half arsed business
6. Or buy a toy that guarantees strong vibrations (mains adapted massage wand for me).
7. Let yourself orgasm. Have a 2 minute break, then keep on with the clit/Gspot stim. Until you feel a build up, and then let yourself release.
