I recommend doings little research. Use the search bar in the top right-hand corner to find some of the older posts about succubi. I personally disagreed with that website posted a few comments above this.
From my experience, I can tell you that there are several misconceptions about them. There is another post currently going around about them, which I would read if I was you. People tend to view them as strictly bad, or like the common misconception about demons- "out to do you harm". I'll say only that I've found most demons and succubi to be individuals with a range of personalities, characteristics, etc. They have the capacity to be good, bad, and all shades inbetween- much like you and I. People like to lump them all I to one category based off the actions of a few, which is wrong.
Take some time to set aside and look into them. It's always interesting. Best of luck.
The succubi are typically female spirits (incubi being the male counterpart) that feed of sexual energy.
However, as Personified said, some people tend to lump them into the same category due to the actions of a few. Like us, they can be pleasant, unpleasant or anywhere in between- not all are particularly malevolent.
Typically, it is said a succubus can either be in dreams or not. Some have said that they have experienced intercourse with a succubus in the Astral.
A succubus is also said to collect semen from the men she has fornicated with. It has often been said that the succubus are not capable of reproduction, however there is controversy about that statement. It has been suggested that the incubi use semen to impregnate human females.
If you find the succubus interesting, you may also want to delve into the following: Al Basti, Empusa, Lamia, Lilith, The Lilin, Mara, Rusalka, and Belili. These are similar figures in mythology from a variety of cultures.
Here is a site you may find interesting, although I can not guarantee its validity.

That site also has more information in tabs on the left hand side of their page.
As also said previously, if you type in 'Succubus' or 'Succubi' in the search bar either on here or Google, I am sure you may find some information on them worth knowing.
today in the 21st century, succubus is a term some use to describe strong females who have a seductive ability, but are able to take control of any situation, using the power of touch. not so demonic anymore, they are more human then you would think with a particular gift, not like the kind on TV.
