Playing away

Sleeping with someone can bring about a complete personality change. That breezy guy you quite liked can suddenly become possessive, clingy and let's face it, a little bit desperate post-sex. To check that your date won't have a personality transplant once you've done the deed, tell them you're thinking about booking a vacation away with your friends. If they become jealous, anxious or awkward, be aware that they may be a bunny boiler in disguise.
