For some people sex is a big part of their relationships, but for others instances of fun between the sheets are few and far between.

This has not gone unnoticed by one US church leader, who has challenged the married members of his congregation to have sex every day for a month.

Paul Wirth, head pastor of the Relevant Church in Ybor City, Florida, is hoping that his saucy suggestion will help improve many relationships.

He explained: "Couples across America are struggling in their relationships, both married and single people.

"For married people it seems like the sex is great up front, but then for some reason life happens. But when you're single it's like you're always thinking about it and you're like, man I'd like to have it as much as possible.

"And sometimes that prevents them from having a great, healthy relationship later on when you do get married."
