Please don’t make posts like this. There are many people with PFS who have solely neurological symptoms, with their sexual function unaffected. You speak of derealisation so severe you cannot drive; if a person has only that symptom but can get an erection, should we be asking them “what are you doing here”? I believe @Mcbbould is one such member who has severe neurological problems but none sexual.
I don’t think you made your post with malice by the way but we must all remember that PFS has a broad range of varying symptoms between patients and within those patients, severity will also vary.
