Something that became clear to me when I was writing on another thread about how subs are not weak... I realised that the reason I would never go into a full time sub position is that I'm not strong enough.

I have a weakness for avoiding responsibility, wiping decisions off on other people. The best cure I've found for that is to be a Dom: the reponsibility is all mine by definition, and I just have to butch up and carry it. But if I were to give myself to someone, I'm afraid I would relax into total passivity and wait for my Owner to tell me when to breathe.
