Of course it does. Lesbians already have only 2 side characters, and only one of them is companion. Meanwhile, gay men will apparently have 2 full fledged companion romances, and straight people, two VIPs of this franchise aside of two sidekicks. And it's going to be even more unfair?
Let's deal with actual facts here. What is confirmed as of now:
Straight males: Cassandra, Josephine = 1 companion, 1 NPC
Straight females: Cullen = 1 NPC
Gay males: Dorian = 1 companion
Lesbians: Sera, Josephine = 1 companion, 1 NPC
Lesbians are not "getting the short end" right now.
What else we know:
There are still three more romances to be revealed and one of them is likely a non-companion, non-advisor NPC. That's it.
There is nothing to suggest that any one orientation is getting "less" or "worse" options than anyone else.
