G-spots exist though (urethral sponge; on the ventral side of the vagina an inch or two in), and so do g-spot orgasms (which feel quite different to clitoral ones). Obviously the idea of just pressing it to get an orgasm isn't going to get you far, but that's just because if you believe that you have no idea how sex and bodies work.
Oh and if I'm in the mood for g-spot stimulation some gentle fingering is absolutely not what I want; I say harder every couple of minutes and I rarely have people dialling it up too fast; this isn't a rough sex thing or anything like that, my g-spot just takes a hell of a lot of stimulating. Gentle is necessary to get things going though.
