keldor...

not all women "ejaculate" infact, those that do are probably in a minority. If I am not mistaken, those orgasms that result in "squirting" is often one triggered by the illusive G-spot. What you describe (contractions and hypersensitivity of the clitoris) are sure signs that a woman has orgasmed.

The most important things that you need to be concerned about is whether or not she is Happy & Satisfied. If she isn't complaining.. I wouldn't worry your pretty little head about it.

And just remember... practice makes perfect
