My Crush Was Shaking Around Me?

I've been known to be a shy guy usually, and have been told by girlfriends that when I was with them I trembled and shook when we were either getting intimate or lusty... I guess I was nervous and kinda scared cause I didn't have gf's until I was 16 and was scared to have my actions be rejected. They always said awe or that it was adorable. So this 19 almost 20 year old man's opinion is he probably likes you a lot, and is shy and nervous.
