Dafuq did I just read

Unless another definition was changed, polyphobia is just a fear of many things.

BUT.. I suppose if a dude is afraid of his wife riding many dicks, or a wife is afraid of her husband getting a lot of other pussy than just hers, then it could be considered polyphobia.

Surprised this wasn't done sooner...

Unless this isn't real, in which case I'm REALLY surprised!

I am all for accepting others and their choices, but the requirement that I be accepting stops at my personal romantic/sexual relationships. Forcing someone to accept sex (which is part of a romantic relationship) against their will is rape. The reason for the rejection does not have to be acceptable, reasonable, realistic, or even explained. If my husband told me he wanted to sleep with other women, fine, but I will no longer be a part of this relationship.
Sexual preferences are highly specific and need to be discussed and agreed upon by the people involved. Sometimes it can include preferences that are considered discriminatory, (i.e. fat, skinny, short, tall, muscular, hair color, ect.). That doesn't make the people who choose not to be in those specific relationships "phobic." Phobic is harassing people for living thier life in a way you disagree with even though it doesn't affect you.

i, too, would be mad at my spouse for cheating
which is perfectly reasonable and not a phobia
i, too, am confused with this new liberal trend
