Customers often ask why they can't buy Adult DVDs on Lovehoney. We do not sell any Adult DVDs because although they are easily available on the Internet, it's not always clear which movies can be supplied legally in the UK.

Buying X-rated movies on the Internet is confusing at best and downright baffling at worst. Different rules apply to different rating certificates and different countries.

We spoke to Customs and Excise and the British Board of Film Classification (BBFC) to get the facts.
