If a guy refuses to fart in front of his long term girlfriend, is that a sign that he lacks masculinity?

It is definately NOT a sign he lacks masculinity but rather that he is polite and consious of those around him. It is embarassing for the girl and the boy to fart in public. Our culture may feel men are more likely to fart in public but not other cultures. It is a great shame in many cultures for men to fart in front of others and is a sign of immaturity more than anything.
