Always been fine/comfortable with one on one convos, but usually bad with group conversations. Especially if the group is a mix of guys and girls.

Home schooled instead of going to a highschool and had no friends throughout that high school period (still dont). I am easily stifled and can't maintain frame, after the approach all the theory I have goes out the window and I go back to being a highschool chode. I feel like a 13 year old talking to girls for the first time, really easily stifled. Is this just an issue of experience? I have shit social skills. Does anyone have any advice for group convos and general socializing (not just girls).
