I sit on the very edge of my seat.its more comfortable?

So my friends joke around all the time about how I sit on my chair. Instead of sitting back with my entire butt on the chair (I feel vulnerable and weird when I do that), I sit like on the very edge of the seat. Basically my back is pushed against the chair...like the top of my sacrum instead of my butt. Does anyone know why I find this more comfortable, or why I do that?
