Self & mate sex-identity in the brain

I wonder whether colleagues in this group would be kind enough to share
with me any knowledge, ideas, references etc concerning the following

I suppose somewhere and somehow in the (human) brain there is a sign, an
imprint, saying someone is male/female, so someone's desired mate is
(usually) female/male respectively. Is it true? Are there experimental

Where in the brain an imprint of this sort exists? When is it established
- embryonic period?

What are the imprinting mechanisms? Hormones? Y-linked and/or X-linked
genes acting directly in "sex identity center"-cells of the brain? Others?

What are the parameters of preferred mate identity: visual? vocal?
chemicals? If visual - forms? movements? texture?

Or  - These questions aren`t the right ones to ask?

Many Thanks!
