The UK has enacted a law that frowns on content that depicts strangulation or incestuous relationships. It is now banned in England and Wales.
The law is not about stopping people from watching pornography, but the government says certain types of porn make people think it is normal to harm partners during sex. Anyone found with physical copies or uploads in the cloud of this content will be fined up to 2 years' imprisonment. The maximum punishment for making this type of porn and publishing it is 5 years in prison.

As adults, it is expected you are fully aware of your actions either right or wrong and that also includes the sexual aspect too. Most people derive better pressure with choking and nobody should judge that, as long as there is no physical harm or unconsented advances from the opposite party.
This ban passes a good message honestly but it does not completely stop people from practicing it, people are aware of their actions and would always choose to do what they like without considering the consequences.
