The way it works in America is that if a woman experiments with another woman, it's 0K. No one considers women to be lesbians for experimenting. But if a guy ever experiments with another guy, he's gay! If he's tries to go back to women, he's BI. In America, if a guy is BI, he's gay, he just doesn't want to accept it.

I lived a few years in France, and I saw something different. Men can experiment with other men, and not be considered gay. The same way women can experiment with women in the USA.
Men in France are considered gay if they go beyond experimenting, and it becomes a pattern.

Women in France don't seem to make a big deal if they know that their boyfriend experimented with another man. The French seem to acknowledge a difference between experimentation and a pattern.
Most women in the USA would have a big problem if their boyfriend experimented with another man. It's a BIG taboo in the USA. For that reason, men who have experimented keep it a secret.

Are the French more open to sexuality than Americans?
