Is the other way around: you know nothing about them. Itās really not that different in any place, cultural diferences aside.
Just treat them like people, because thatās what they are. Andā¦ okay, man, lift, go to places, speak, try to make yourself more interesting. Go for a sucubus if your path leads you to one, but not as a replacement for girls, because, trust me, thatās a very bad reason to do it. Also, women are awesome and you donāt want to lack that awesomeness in your life.
Thank you
The candle is a gateway! Unless you are good enough at trance work to be the gateway you have to use a gateway for the spirit to come to you! It doesnāt have to be a candle! It can be burning incense! If you canāt burn anything then use water as a gateway!
have a bowl of water and place the petition in it with your blood! Meditate on it and see if you get anything! Its just a suggestion am not sure if water send off would work with lilith!
I am afraid of seeing something 
I am very afraid to see someone in front of me or a cloud
Can I use my imagination?
Lol! Then donāt do it! They hate it when people are afraid
Why do they hate when people are afraid? It is a natural thing
Fear is a natural thing as it is an instinct
Imagine someone calling you but scared of you! And you get to feel everything about them. What they think of you. What their fears are. And multiple that with a sensitive nature! Thatās how they are! People gets into this and because of their fears and lack of knowledge they either get lucky and get someone who understands them, or get nothing, or get an entity who leaves them with a horrible experience! Or even manifest their fears!
If you arenāt in the right state of mind donāt ask for a relationship! Especially from a spirit!
You need to be prepared for anything paranormal to happen to you and first and foremost you need to know how to protect yourself!
How can I protect myself, please?
You will have to do your research on that! There are many posts about protection ways! See what works with you! Also start with your meditation work!
You scared me more! 
Okey i will do thank you so much brother
you mean protecting myself from demons? What is the reason that will make them harm me
I am here for learning, I am looking for knowledge, fun and friends
lol! Havenāt you read peopleās posts about them being attacked and parasites and such?
Once you tap into the astral you never know what youāll find! Sometimes its your own creations sometimes others! So keeping a guard up and shielding before you start anything will save you from traumatic time!
Its not from the spirit you make friends with but from others who would come to feed on you! Also if you call someone powerful you gain their respect when they see you powerful too!
You could structure a thoughtform lover, that will avoid all the risks of demons completely, she may take on life of her own over time so be prepared to let her go when you no longer want to have fun with her.
Get to the point where you can see her (in your mindās eye) and feel she is the same each time, then make a new topic asking how to work more with a thoughtform being.
This is my opinion, not āadviceā - it seems to avoid some of the pitfalls you are concerned about, and could be just as useful.
Lucifer may teach you how to do this, and can grant you succubi or incubi (or both) (or whatever gets you going really). He may also teach you other astral sex techniques that can be used for seduction magick (which people sometimes forget can be used with an existing partner), in case you ever want some 3d to go with your 2d.
However you go about doing this, youāll benefit if you treat this sex magick similarly to other forms of magick. You could just let the sexual energy go wherever, but you could also use it for manifestation, just like with other forms of ritual magick.
Be wary of becoming obsessed, just as with any other sexual partner. The sensations that you can experience are very enjoyable, and it is not uncommon for people to refuse working with other spirits out of a sense of being disloyal. Sex magick is just as effective as any other magick, but if you feel that a spirit partner is becoming jealous, then that is either your fear being projected onto the spirit, or that the spirit is an imposter seeking to drain you of your energy while providing little in return.
You may find the book Adventures in Sex Magick by Damon Brand helpful as well. There is no demonic magick in the book, only angelic, but there are many ideas which can be applied to demonic sex work. Tantra would also be good to look into.
Nice waifu btw
