Fancying a celeb 'can improve sex life'

Girls infatuated with certain celebrities - be it Ryan Gosling or Robert Pattinson - may want to stock up on female condoms, as it appears such crushes can boost a person's sex life.

Andrew Marshall, marital therapist and author of I Love You But I'm Not In Love With You, has claimed such admiration shows a relationship is a healthy one, the Daily Mail reports.

The expert said if a person imagines they are being held by a famous hunk such as Brad Pitt - famed for roles in hit films such as Fight Club and Snatch - when in their partner's arms, this is not necessarily a bad thing.

Mr Marshall explained: "You need to be as creative as possible when it comes to your love life. If you believe you're only allowed to find each other attractive, that's an incredible straitjacket."

Celebrities are ideal fantasy figures as they tend to fit into archetypes, he added.
