In tradition, gender is considered an indicator of energy, divine potential. Previously, they used to worship Lord Shiva in the form of an idol. Pashupathi statue found in Harappa ruins can be examined.
In the story related to the incarnation of Venkateswara Swamy in Varahapuranam, in the Bhrugu Maharshi curse Siva, "From today onwards, there will be no poojas to your Linga only, not to your idol". It means before that, the idol will have poojas.
The custom of worshipping Shiva Linga by considering it as the image of Shiva is ancient.
