Pleasant surprise

I am currently reading Fairyville by Emma Holly. It was recommended by a friend who knew how much I love reading M/M fiction (not that I didn't already read EH ;) - loved her book Menage).
However, reading the blurb, would you have guessed that this book had a M/M relationship?

Zoe Clare is a medium who has no trouble communicating with the dead—or with real live fairies, for that matter! But she can't seem to get her feelings across to her landlord-slash-manager Magnus Monroe, Fairyville, Arizona's most eligible bachelor. She's tired of his erotic antics with every woman in town but her. So when her high school flame returns to town, Zoe is more than a little vulnerable to his charms. How Alex broke herheart is a scandal no one in Fairyville has forgotten. But even if Zoe isn't ready to forget, she's willing to forgive. The rules they're about to break will bring out the jealousy in Magnus—and the astounding truth.

A menage possibly comes to mind, but not that one of the main characters would be bi-sexual.(I don't want to ruin the story or the twists that are coming along with every chapter)
Then I found quite a few comments on Amazon about how readers enjoyed the story but the M/M scenes really weren't their 'cup of tea' and wished that they'd known about them. (and let me tell you that the sex scenes are graphic and wonderfully done *drool* )

Now, I'm only half way through the book (won't take me but another day to finish it at this rate) but have absolutely no complaints about it. Mainly because I was aware of the gay scenes and eager to read this book (so far it's hinting around to a possible menage or more *eyebrows waggling*)

My question to you...Do you feel that not informing the readers about same sex sex scenes deceitful? Do you think it would gain or lose readers? Or perhaps have no effect at all? Have you as a reader come across other books that have done this?

I just thought it was an interesting situation and wanted to know how others would feel.
