Sex questions for females

I have been always curious about female body during sex. There have been many myths and less percentage of women who actually feel satisfied. One myth being the g spot. Does that really exist? Since I am fckin virgin and have just tried only masturbating it was fckin painful at the very end but it was okay when I first penetrated myself, even felt a funny feeling. But I couldn't find any shit, so called "g spot" that's supposed to make you go crazy or something.
Not one bit of pleasure. Does that also even exist? Pleasure? I feel like sex is mostly for men's satisfaction.
One more question, do women even ejaculate like men do? Except of the white lubrication women lets out when feeling aroused.
I feel women only like squirt? Which I suppose is just very little matter of urine and mostly water, because of the constant pressure being applied in bladder. I have so many questions, because I feel like reading all those smuts and everything feels like I have been lied about how women body actually feels and works during sex.
I have heard and researched that very less amount of women actually really feels satisfied and gets their orgsam they desire.
Well I don't know. I want y'all answers and opinions.
