I love this particular topic from Long and Short Reviews, as one of the benefits of writing romance, especially erotic romance, is you can get away with humorous titles.
A favourite of mine is "In Appreciation of Their Cox" by Janine Ashbless. It is, of course, about the cox of a rowing team who has a multi-way celebration after the team win an event. I had to buy it as soon as I heard the name.
Another is "Here Be Sexist Vampires" by Suzanne Wright. Also explicit, but a really great story with a kickass heroine who takes no nonsense from the sexist vampires around her.
And I had to include my own, which is downloadable as a freebie from the Totally Bound website - "I Can't Believe You Used My Butter". I had wanted to use that title for ages, and the chance to do a free short story inspired by "Last Tango in Paris" was irresistible.
I'm interested to see which titles everyone else will share!
