Alright when fingering my girlfriend I can't find the g-spot at all. What does it feel like and where is it located at after inserting my fingers into here vagina. When I do finger her and stick my fingers all the way in I feel this round thing all the way in the back what is that? And when I move my ringer accross it she says it feels really good. Its like in the middle/top and its like a big round thing.
