As I always say - how do YOU prefer it? I know you felt odd in the gym shower, but overall, did you like the way it looked/felt shaved?
Do you want to grow back the full bush you were sporting before? Maybe you'll find a length during the grow-back process that you'll like.
And again, it's just hair. Shave or cut it and it grows back. Grow it long and you can always shave or trim it again. It's not like a tattoo. It's a temporary change and you never have to commit to any one style.
But personally, (not that it matters) I thought the shave looked great ;-)
