Incubus and succubus
Incubus and succubus are demons that replicate the sexual functions of a man or woman’s body, and seem to have ‘intercourse’ with their host. Incubus resembles the male body and is known to approach women, and succubus replicates the woman’s body and approaches men.
What are some common entry points?
From my experience with working with women who have had the incubus spirit, most of them opened the door through an ungodly soul tie (formed through fornication or adultery). I believe they can enter through other routes, but this one I have encountered more than once.
