I'd say if it sounds/acts/smells/looks just like a sporran, then I'd wear it, no matter who it was originally intended for. For the OP, to me personally, the one pictured does not qualify.

As far as opening doors goes, I'm a victim of my upbringing, and will always hold the door for a lady. I'm not sure if that's chivalry, or just the fact that if I hold the door, I get to watch her walk past.....

Have Fun,
