All those hobbies of yours have nothing to do with whether you can get a girl or not. Its your hobby, its your passion, and you should be proud of it. If you're proud of it, you'll find a girl who wouldn't look down at your passion. Don't bother accepting any other girls who can't accept your passion.

Whether you get a girl or not depends more on your social skills, be more confident in yourself. Don't try to force yourself into a relationship, its better to find someone who can relate with your passion.
