You are screwed, they know about this issue and have called it solved.
Basically the "fix" is start over again losing all your saved playtime and spam male female options a few times hoping the flag for male sets right, then start the game and if you are still getting the female dialog start over again spamming the male and female selection and hope it sets right, keep doing until it does.
I am not kidding this is the solution they say fixed the problem, see this link. http://answers.ea.com/t5/Dragon-Age-Inquisition/Gender-issue/m-p/4004245#M4336
