A lot of conjecture on the gspot/squirt thing,but a couple of years back my OH hormones went through the roof due to menopause,long story short,our sex life went through the roof and all her previous inhibitions disappeared.
One night I hit all the right buttons and she started squirting,she was embarrassed at first but went with it after I reassured her that I loved it(couldn't believe my luck as it's one of my biggest turn ons)
I found if I fingered her while massaging her clit she would squirt almost immediately and could keep on doing it the more I did it to the point where she would nearly pass out.
I think once a woman can do it ,it's easy because now she squirts even with just penetration and no fingering.
The clit/fingering combo is now off the menu as she finds it too intense,and as per usual with women,the hormones have gone the other way and sex is a rare occurrence again,hence me dipping my toe back into punting after a very long break ,and joining this site,but that's another story
