Hinduism restricts promiscuity for men and woman.
Bhagavad Gita 2.62-2.63:
While contemplating the objects of the senses, a person develops attachment for them, and from such attachment lust develops, and from lust anger arises.
From anger, complete delusion arises, and from delusion bewilderment of memory. When memory is bewildered, intelligence is lost, and when intelligence is lost one falls down again into the material pool.
Regarding khajuraho As per upanishads, the sculptors created those pieces of arts is only outside the temple because it signifies that all those feelings must be left outside the temple, before entering the inner sanctum. There are no such sculptures inside the temple. The sculptures are also on Konark temple's exterior. It is a metaphysical symbolism. Hinduism recognizes the role of sexual desires in human lives.There is a difference between Nudity and expression of beauty and pornography. What appears in Hindu puranas are the expressions of genuine beauty and not pornography.
