If I had someone cool to have sex with but nothing else, like no attachment and no nonsense, I wouldn't thumb my nose at that. A nice girl, who I know nothing about and keep it that way, who comes over when she's in town, and nothing else. We don't talk about our lives at all, only the moment, and when we're done we say goodbye with a kiss and a big smile, and a joke.
And if there was no next time at least we parted happily, with light hearts.
