Sub personality, sexual Dom?

My family and friends have never classed me among the “confident” or “charismatic” types. I’ve always been shy ig. But since the beginning of my sexual awakening I have always felt that I would be the dominant party during sex (my taste in men furthers my theory). Basically any time I see an attractive man by my standards, the first sexual thought I have is “god what I wouldn’t give to see him in a collar”. I’m just wondering how I can be a non dominant personality and still have these desires. Thx.
