Unwanted entity/spirit?

Thanks for replying, I'll get back once I've tried both.

Typically what you should do when you think you have an entity you don't want around is banish, cleanse, and then protect in that order. That is a highly repeated phrase here on SoM.

Is it possible that it is friendly as it only made me 'happy' and increased my libido a bit, only thing that scared me was the face of some sort of demonic dog toy or something like that?

I don't know much about Incubi other than that they are sexual beings that supposedly feed off of the energy of the people they attach to. Some people consider them demons. I personally would not want a spirit being feeding off of my energy, demon or not. I don't think he would be 'helping you' without wanting something in return.

May be a hallucination then, haven't felt deprived of energy since it started, nor overnight

That's definitely a possibility, or just very vivid dreams.

Spirits never actually physically manifest. Sexual intercourse would require actual physical touch. While I can't speak much to the nature of succubi/incubi, I would think they would be most likely to interact through dreams. Whether or not an actual separate entity, or a manifestation of one's self made into a thought form of sorts through built up desire that is not acted upon, I cannot say. It's never been something that interests me. As with any spirit that maybe harmful, cleanse, banish, etc. Or don't, it's your prerogative.

Personally I absorb their negative energy into myself and turn into my own magical energy. It’s takes away their negativity and they leave me alone after that. If you want I can tell you how if this idea interests you.

Thank you for the kind offer, but it appears the incubus has left me alone but that wouldn't explain why my brother said he could feel something watching him or walking behind and following him until he went to sleep, where he could feel something touching him in certain places. As I was writing this I think I saw something on top of me as I'm lead down?

You could always try the old traditional way and use a honey jar ritual,
