Is this a relapse?

Yes imo it's a relapse. What are the terms of your reboot?

 

That's why I asked what were the terms of your reboot.

 

Well then that kinda is a relapse if your doing hard mode since you were edging but it's up to you.

 

Glad you're wearing clean underwear, but, if it causes you problems with feeling stimulated, why are you wearing tight underwear?

Why do we wear underwear? What is the purpose of it?

 

Well then it's up to you.

 

Well you could also do that and stop yourself and not o, I'm not sure, I think.

 

Sounds funny. How put it in those words: "I like stimulating my penis with wearing fresh washed underwear"? Or put it in this question: "Would you, dear Iggylshness, prefer to make your clean underwear not so enjoyable by first rubbing it wiht your hands rather than wearing 2 times a day clean underwear?" Does your mind look forward to more stimulation or does your mind look for inner peace? Last one would fit very well to No-PMO.

 

There's a good tennis arm joke somewhere in here.

 

I guess your underwear is made of cotton (at least 9O %). So why does it irritates your penis and my clean underwear does not irritate my penis?

 

It is.
Some people take it to mean any form of self stimulation that feels good. If that is what it takes for them to stay PMO free, more power to them.
If they are your fetish, you may want to consider underwear without the memories.
