Astral sex involves having intercourse with another individual spiritually, using spirits as a medium that makes you think you are having sex with another person when in reality, you are having sex with a spirit that is feeding your life energy. Bodily fluids are transported from the male between two spirits, who then impregnate the female with altered semen. The resulting child is a Cambion. A similar manner happens with incubi and succubi, the only difference is that you are willingly having sex with a spirit while you are awake.
