Length girth for certain spots like the g-spot
Hey guys, I’m sure you all know what the g-spot is and where it is located at. Now I remember seeing some posts mentioning certain other spots, that are further in etc. Now my question is, or are, does anyone of you know how long a penis have to be to hit those spots? (Lets say on like 50% of the women or something like that?) Does anyone know any good links that give some more information about them? Does anyone know what exactly happens if they are stimulated?
Thanks in advance,
