Once and forever
I'm guessing Shino is a buck (male deer). if you look at his profile, he has antlers. Doe (female deer) don't have antlers.
I Shino is wearing a woman’s yukata (as far as I know male animals can wear any clothing but stick to their assigned gender or unisex clothes for base outfits) and has an unambiguously female name (yoshino) . She also seems to likely be based off a Kirin, or other Japanese mythological creature, not a deer.
as pointed out by others elsewhere (there are so many threads discussing this, sorry to be repeating), the deer species in the game is also used to represent animals like antelopes, in which both the males and females have horns (they do not call them antlers in this case I think)
