I fail to see the problem, It's still Fire Emblem, and if you read the Iwata Asks from the game you will that they took the complaints about Awakening's story to heart.
Also you know that if you feel so unconfortable with a part of the human anatomy you can just not play this part of the game right? You can just play the history normally.
That is what I did with Awakening, play just the main missions and some paralogues because I didn't care for the relationship system.
Again, I fail to see the problem here.
