Good for you for not having sex intoxicated. Just be careful as you’ve only met twice and you can’t possibly know what’s regular for her. Typically people who don’t drink don’t use alcohol to calm themselves before getting on a road and don’t drive intoxicated. Very reckless of her. Insisting on drunken sex isn’t very attractive either. I am not telling you to end it but proceed with caution, she sounds more trouble than it’s worth.
