You're on a first date. It's going well. He/she is amusing and you're hitting it off, and they are attractive. Then you notice it, or maybe your date points it out. A physical imperfection/shortcoming that you hadn't noticed when you were asked out. Which of these physical 'differences' could you overlook, which you could proceed to following dates? Anything you don't check it's because the physical 'difference' is too weird for you, and like it or not, it's kind of a dealbreaker
Note: apologies to anyone, if you suffer from any condition mentioned above, or know someone who is suffering. Not trying to belittle the challenge you or a loved one must face. Simply seeing how well people can overlook the physical when romance is on the horizon.
