Why am I a submissive

I been asked why are you a submissive
I'M playful, I need someone I can trust and relay on who's not me.
Someone bigger, safer, and reliable not afraid to take charge.
Someone strong enough to hold me, and affectionate and wise enough to understand me.
To know when I need a spanking or if I need a cuddle or both to get me out of my head and back and back into life.
I have a need to release everything to this person. This makes me a submissive.
That's why I'm a submissive. It's who I am.
