I will start with your question:
QuoteMy question is how can i regain this feeling best without losing progress. Do i need to stop using the extender and stretching, and for how long?
Can have many reasons for losing feeling, progression of the disease is one of them, main culprit I will say.
Personally I don't see nothing in your treatment that may cause the loss of feeling, I was continue the treatment, but I am not a doctor. You should talk about to a specialist.
Regarding CoQ10, I don't know your age (no age in your profile), but if you are over 40 or near to, better use Ubiquinol.
Our body uses Ubiquinol, the capability of our body to transform the Ubiquinone (CoQ10) to Ubiquinol falling drastically after 40.
By the way vitamin E will not make you any bad, but from what I learned on the forum will not help also with the Peyronies.
Also want to congratulate you with the progress and wish you continue improving. :)
It show AGAIN that early stage treatment helps :)
