Pussy: Hands down, the single best word in erotic romance for the female genitalia. It’s hard and works well in sex scenes but it can also be soft and easy to make it sound sexy. As a man, I can tell you, it’s sexy as hell when a woman uses it.
Her: “You want my sweet pussy don’t you?”
Him: “I am going to take that tight little pussy apart.”
Sexy: “Her succulent pussy was the portrait of pleasure.”
Derogatory: “He’s a little pussy.” or “I wouldn’t touch your pussy if you paid me.”
You get the picture.
