swearing in front of the opposite sex is a no no......how I grew up. If you are a girl and swear in front of men, they might think you are a bit wild and willing to do something you are in fact NOT.
If you are a man and swear in front of a girl then she might think you are too rough and an idiot.
Men swearing in front of men ....none of them will care.
Girls swearing in front of girls, they will all laugh.
