Good to hear. I have noticed the same things you have. Erections easier when sitting, symptoms better in the morning, etc.
Sometimes I will wake up with some libido and it will just die later on in the day. Or sometimes if I wake up with good libido it will get worse and worse throughout the day. I am rather certain that these things are the result of pelvic tension being worse while standing and awake. When my symptoms are at their worst, though, I wake up with zero libido since pelvic tension is high even when I’m sleeping.
I get the knee pain as well sometimes and it seems to be caused by interference in the joint due to muscle and fascia tension.
