Zachary Quinto comes out as a gay man.
This obvoiusly leads to the question of whether there are gay Vulcans. From the Wikipedia article “Sexuality in Star Trek”:
In Peter David’s Star Trek: New Frontier series the character of Burgoyne 172 is hermaphroditic and bisexual, s/he has a brief relationship with helmsman Mark McHenry before entering into a relationship and fathering a child with Dr Selar. In the same series Selar’s brother briefly features as a gay Vulcan, his father disapproves of this, though seemingly not through prejudice, but because he does not see the logic in sex without procreation.
Now that’s not cannon, but it illustrates the logic of the question. I personally don’t see what sexuality has to do with procreation. For example, Quinto-as-Spock’s relationship with Uhura doesn’t seem to be about procreation. So what say ye, nerds?
