Yes. At times you’ll feel zero interest in sex but then one day you’ll come across a trigger and the feelings will come back like a full speed train and you’ll feel like you have zero control. You need to have a game plan set up for when those urges come back.
It could be also possible, that you are in a flatline. No errection or attention to porn or sex. I had it sometimes and took 1 or 2 weeks until the desire returned.
I am different and feel tremendous urges, but maybe consider youself lucky that you don't (temporarily) since it will be easier to reboot? Congrats on Day 3, I'm on Day 3 too
