Unlikely women or men in a Roman fort were using this object to insert in their vagina or anus for thrills. Or indeed to torture someone, they had much more vicious instruments. The phallus was the image of Roman power, and was literally as common as MacDonalds Golden Arches are today. Much more so. This will freak some of you out, (I hope it does), but the cock was as wide-spread in the Roman Empire as the crucifix or cross in Medieval Europe. It was a symbol of a value-system.
