I wouldn't talk about all my sexual adventures in an MMO, and neither should a homosexual.
This sums it up. There is no reason to have the words 'gay' and 'lesbian' in the database for Star Wars. The only uses they'd have to the MMO population is to use as insults, which is exactly why Bioware wanted to sensor them.
Having the conversation of something like "Hey I'm gay, that cool with you?" Why the hell would that be important in a computer game??
