Yeah this is a thing. I’ve talked to so many people in separation who experience the exact same loss of interest.
The sexual energy between twin flames is pretty much the most intense type of energy you can feel. After experiencing that, trying to manufacture attraction with someone else just… doesn’t work.
I tried the same thing when I was in separation. Thought waiting for them was a version of chasing so I tried to force myself back into dating because I thought it would help me ‘move on’ or whatever. Complete waste of time. The connection with these people couldn’t sustain that same pull even when I wanted it to. My body just refused to cooperate.
I’m sure they were all very nice people but I was just bored the whole time and it wasn’t that they were boring… I just couldn’t have a spark with someone else.
There are people who are physically intimate with other people. You’re not wrong for doing that. There’s no right answer. But the ones who stay celibate usually say it wasn’t a choice they made consciously, it just happened because nobody else registered for them anymore. That’s basically what you’re describing. You’re not alone in this.
