If what they show (censored) on their web site is any indication (yes, I checked), the game they want to sell is quite sexually explicit. There isn't really anything comparable on Steam right now, envelope-pushers like Mass Effect and The Witcher included.
The publisher may be right, in one respect, that the game she is trying to sell might be labelled "erotica" in some places. But in the United States, it would generally just be labelled "pornography", and selling pornography in the U.S. tends to get one painted with a brush such that it can become difficult to sell anything else.
I can't really hold it against Steam that they would choose to take a pass. Steam has offered other games, especially independents, that contained some fairly risky content. Sexually explicit materials are just a bridge too far.
