So I've been at this no PMO thing for a long time. Here is my update:
About a month ago I took one Levitra, and had wonderful sex with my wife. I didn't take any more Levitra after that.
My wife joined me for 7 nights in a row and I was able to have sex every single night. I was happy and really thought I was "cured".
On night 8, she came, and I was just wasn't into it.
It's been a month, and I've been down in the dumps ever since. I keep second-guessing myself as to whether those 7 nights were really natural or not.
