In regards to S.A.F's posting, yes I remember clearly getting wood before my testes began pumping out T. In the transgender community, those with regiments that eliminate T (usually through oral progesterones, shutting down LH from the pituitary) are still able to get wood. The complaint is spontaneous erections, EG morning wood dimish. Voluntary wood is still achievable through visual, mechanical stimulation, ect... I think that ED then develops over time as the corpus cavernosium begins to atrophy and fill with adipose tissue because of a lack of nocturnal erections. I heard nocturnal erections are an important part in maintaining healthy physiology of the erectile tissues. Anyways, side note. For those truly concerned over both hairloss and ED, I would say that a small dosage of v**** nightly before bed to provide good blood flow to the wang should compliment any regiment that causes ED.
I also think that maybe Velluti learned to adapt to sex w/o T, he psychologically controlled his libido more than T did... Just my two cents.
