No, I don’t believe we do know this, but perhaps a follower could add information?

Trying to meet incubi or succubi is REALLY dangerous. Well, if I say dangerous, I mean you have to look out for certain things. You can indeed meet them, but they’re connected to demons, therefor, you need to watch out. Second of all, some of them are monogamous. Hence, if you have a lover or something of the sort, they might end up getting hurt. The same with people who might have a crush on you! Third, they stay with you for a life time! They won’t simply go away. Once you summon an incubus or a succubus, they’ll stay connected to you. They don’t come and go like Gods might do. However, they will care about you like an actual lover would. You can also decide what they look like, since incubi and succubi form themselves to your wishes.
If you still want to summon an incubus or succubus, I’d recommend you to look at this page. They’ll tell you the exact same stuff I told you just now, just more elaborated. Just be careful and respectful to being like that. They don’t like rudeness at all..
