Shyness is rarely the problem when it comes to a lack of d/s/r. If girls have never expressed interest in you, or worse been actively hostile towards you every time you tried to form a connection, it's only natural to want to avoid them. On the other hand, if girls have made themselves available to you, any innate shyness you might have would easily be overcome.
