I generally use a name that's very close to my wife's name, and the names of her old lovers. That way (at least for me) it's easier to keep it pretty close to the actual experience (I only write about my wifes adventures-no fiction) Hope that helps
The names on the spam in my mailbox are pretty creative. I've never used them in a story, but it always makes me laugh to see the list of imaginary people in my junk mail folder.
