My reaction to the first three stories has nothing to do with prudery, but stems from their lack of depth and complexity. My favorite, Robin Schone's story, is the most erotic, the most daring. The first three stories aren't romances. The relationships are based on lust, and I'm not convinced that it ever gets past lust. The protagonists treat each other cruelly and have little concern for the other outside the confines of sex.
Relationships based on lust without love and without caring are meaningless.
Bertrice Small's heroine falls for the guy because he's well equipped and has given her multiple orgasms. If erotica is well written, it won't cause you to laugh out loud, but every time I read about Dagon's love lance,' I cracked up. Susan Johnson didn't convince me that her characters had really fallen in love. I guess I blinked in the wrong place. Thea Devine's hero is so controlling that he doesn't mind degrading the heroine, as long as she ends up hot for him.
