Today the term Tantra has become very popular and is thought to be mostly related to sexual intercourse.
But Tantra is a very ancient spiritual tradition originated in India 5000 years ago and is focused on the total expansion of consciousness, so it is not only about sex, although this is part of the tantric path.
It is important to know that Tantra is the union between the consciousness that impregnates everything and in many occasions it is asleep, also known as Shiva and the power or energy necessary to awaken it, known as Shatki, so the Tantra seeks to channel and move your energy so that you can awaken your consciousness at the time of being able to integrate each experience and be a balanced person.
