i think that it is generally accepted that libido is pretty much
established by testosterone levels at puberty, and that thereafter
it declines only slowly if testosterone is lost after that (in
humans; in other animals libido is tightly linked to testosterone
with no psychic component).  Libido and direction (sexual orientation)
of interest are different.  Libido only very slightly reflects t
levels (which do not vary much) and direction does not.  this is
all pretty well covered in many books--a few years back, by John
Money and Annika Ehrhardt--and you should be able to find a lot
of information at Hofstra or at the St. Johns library (the latter
is actually pretty good).
