Larians have already confirmed that there are going to be romances. Players will be able to romance every companion - no matter the gender. One of the things which will count is the companion's personality. Some may not agree with your choices and as a result won't enter a romantic relationship. It is also worth noticing that the romances will be much more complex when compared to Divinity Original Sin 2. They want to make it deeper so that it won't just be a simple quest which awards the player with a romance.
