This book is akin to other "best of" series. However it is not for the unadventurous. It has many stories which were not always "hot" but unusual or took people outside their comfort zone. This book is not for Prudes.
To be brief, about 40% of this book is gay erotica. It's not disgusting or anything. It was very well written but I didn't listen to all of it, because it was boring. If you have "erotica" without the "erotic" all you have left is "a."
I suggest you have 3 versions. Straight, gay and mixed. This way people will know what they are getting.
