You have to make sure to have sexual energy of minimum 360+ each day before going to sleep. I'm not sure about this, but it could be that your daily reserve doesn't increase when you don't sleep (before midnight?).Thank you for your response, even with that high amount of succubus energy, I have only a food energy reserve for two days...
But how increase my "food" reserve ?
But i never even care about that when going succubus. All you have to do is have sex a lot every day. If you have problems finding people to increase sexual energy, go to the community center, female bathroom last stall and do anal sex. In generel, i made the experience that anal is best to increase sexual energy. And as i said, when you do have at least 360+ sexual energy a day, you should be fine. To be on the safe side, do a testing, load up energy, check your reserves, go to sleep and check again. Then you will see what is needed.
