I knew about that subreddit but actually looking through it... it looks like a pit of despair. I'm obviously not the target audience, but I don't see how inventing a whole lexicon is conducive to helping any newcomer. I guess it works for some people.
Be glad that you don't have sexual problems. If you do as a man the response of most doctors is to offer you free viagra samples, which you can use three or four times and then you need to buy the real thing at an obscene price.
But really, that's obviously not the problem for lots of men in their 20s and 30s who are in reasonable health.

So some herbs have benefits, but it's hard to tell which as this industry is full of BS.
7) nofap, discussed in the last few pages;
8) I've read of people having success with long-term water fasts. Just yesterday, I read a long essay from someone who recovered from a specific form of ED, called "post-finasteride syndrome" with a 21-day water fast. It's a response some men have to propecia/proscar, they respond very badly and get awful side effects. He also had brain fog which he recovered from;
