An option to be flaccid while walking around naked would be fantastic. A lot of people don't like walking in the buff because their cocks are always on Viagra that lasts longer than 4 hours. It's not exactly appealing to see entire rods poking out around the place either.
We know this is already possible, because of the standing idle animation with the avatar's hands on the backs of their heads, so why not make the option when wandering around, too?
I think this option should be available for both Avatar Genders.
