You’re definitely not alone, and no, this won’t be like this forever, but it does transform rather than just fade away.
What you’re describing with your body remembering them and the physical need being that intense during no contact… that’s textbook twin flame separation energy.
Usually, we get signs they’re thinking of you sexually, and we’ve already had a thread on arousal during separation. So no, you’re not alone.
The sexual frustration during separation reaches really high levels and stays constant or even grows because your soul is literally responding to the lack of completion with your other half. It’s not regular horniness. Your root chakra is probably going crazy right now, and if they’re thinking about you sexually (which they likely are), you’re feeling their arousal on top of your own through the energetic cord.
The push energy does feed on itself. The more you focus on the lack, the more intense it gets. Over time, the intensity doesn’t disappear, it… shifts in quality. With healing work and surrender, it becomes more manageable. Less chaotic and overwhelming, more grounded and clear. You’ll still feel that magnetic pull and the sexual energy will still be incredibly strong, but you won’t feel like you’re drowning in it.
