Couple arguing       Photo:josephshaub.com

David Mason, 30, took his own wife Brenda, 31, to court after she rationed sex to once a week because she was scared of getting pregnant for a third time.

Mr Mason, a mechanic from Basingstoke, Hants, initially won his case in 1980.

But he lost on appeal when judges decided no court could rule that Brenda was being unreasonable.
