Even if I’ve had experienced the darker aspect of a succubus - including the presence of an incubus - I have never experienced a malevolent kind. The incubus is of a different nature than a succubus, though. Some of them seems to be dominant in their nature, persistent and spot on in what they want. But there’s also experiences of shy and passive incubus entities, which did coin the phrase of “gentleman spirits”.
Their dark currents is, indeed, very cold, compact and just as solid as a human, physically. Having sex with that kind of presence can be scary and intimidating for someone unprepared or when it’s non-consensual. Consensually, it’s even more enjoyable than the upper levels of their energy currents, if that fits your sexual preferences, of course.
Other than the sexual aspect of their darker manifestations, they often dig deep to find what scares us the most, and I’ve had quite the experience of that as well. The difference is that my experience was in a controlled environment with the intent to learn and familiarize with all their manifestations, rather than being controlled and feed them with fear. When these kind of manifestation is in control and the entity is consciously aware of what they’re doing, without going primal within their darker nature, the experience is quite awesome. It also shows how intelligent and developed an entity is, when it has the power to control and tame it’s own primal urges. It seems your visitor isn’t that highly developed, just yet.
I would also recommend you to proceed with the banishing ritual, and maybe confront it by asking questions. Of course there’s other ways to proceed, but then you have to learn more about energies, the different currents and it’s functionality. You can even reverse the experience to your own advantage, which could scare the shit out of that entity to submission, but that isn’t recommended for starters.
