Why do you succubi anons want to feed on sexual energy when there are other sources of energy that are more available and richer than pent up horniness? What did you do that you aren't welcomed at the all you can eat buffets and have to wait for invitation of lonely anons?

The invitation is not necessary is to avoid  this people, taking sexual energy is super fun, not only because it feels good, it's also one of the most interative ways to do it. I like toying with my prey. Sex has some of the more complex interactions human society has created. It's also concentrated and raw.

But can you still feed in other ways? What do succubi plan when there are no more creatures able to interact with spirits and provide them with nourishment? It's placing all your eggs in one basket from my human point of view.

Sexual energy is a form of refined and directed cosmic energy, the key words there being refined and directed. Instead of being a low quality scatterer spray of energy, it's a focused beam of super concentrated energy. You'r body absorbs, compresses and directs this energy through arousal and sex. Succubi are not physical beings, because of this there are energies they can not interact with, humans with physical bodies can, we're basically a conduit between them and things they need but can't access. It's a fair trade, companionship and knowlege for the energy in question. They can access other forms of energy but it's just more efficent to do so through this kind of exchange.
