I used these vague concepts because
1) I don't want to lock this into a specific religious system
2) It's not entirely clear to me how it's transformed
I think the important thing here right now is not if you spent it or not, but rather you should focus on transforming what you have to an eternal form of love, and if you lack energy because you spent it, replenish it through devoted practice. I said mundanes have only this one portion. That's because they by their very nature do not try to change what they have, they only use it and die when all energy runs out.
Also pay attention to the words here. Merely looking at, or thinking about, another person, can be a mortal sin. Actually having sex with them isn't the dangerous part, it may not even have a negative effect if you didn't care about it at all (which is unlikely, but there is a technical difference here).
It shouldn't be too difficult to find out if you contracted a sex demon and borrowed energy by them unknowingly. They keep tabs on it so just express in a telepathic broadcast that you want to pay this off and can offer better energy in return if they support you. They'll appear to you and help you. I already did this much, as long as they can gain something from it, they don't care how you pay off a debt.

I'm aware this list is associated with the catholic church, but personally I find the seven mortal sins and the discussion of what they entail to be the most useful aspect of modern western religion. Take a look at them and you may find that a lot of seemingly minor things are considered mortal sins. The ten commandments aren't all that useful imo, it's better to know what to avoid and why. This all deals with not wasting your "one love".
Qi gong and Taoism has other terms for this, but in this case I prefer the more societal western way to discuss it.
