The sexual energy between twin flames operates completely differently from regular attraction. Most people find that normal relationships fade over time. You get used to someone, the novelty wears off and things settle into routine. With your twin flame, it works in reverse.
The connection is based on recognition rather than discovery, so it actually intensifies as you become more familiar with each other.
It’s not that you’re forcing yourself or making a conscious choice - your energy body recognizes your twin at a cellular level. The sacral and root chakras activate specifically for them, and other people just don’t trigger that same response. Leaving everyone else feeling “flat” or “empty” by comparison.
The craving you mention is part of the energetic exchange that happens through what’s called the twin flame cord. The energy passing between you can manifest as intense sexual thoughts, spontaneous arousal, or just this persistent pull toward them.
