Anybody else was incredibly stuck up as a teen and as young adult?

I remember being so stuck up about things generally concerning life, especially about sexual things and other interpersonal stuff. I could not let loose at all, always had to intellectualize everything in a very cringy way. Maybe it was because my parents never taught me how to socialise properly and i got nearly all of my information about how people are behaving with each others from books and newspapers. My parents were not even particulary conservative or from a repressive religion or anything.
