I agree, and don't think it could possibly be claimed or is relevant here.
Just by the way though, efforts are being made in the UK to make it impossible to claim strangulation was a part of consensual sex. From an article in 'Counsel':
'During the reading of the Domestic Abuse Bill in June 2020 Jess Phillips MP proposed that non-fatal strangulation be made an offence by adding that ‘A person (A) commits an offence if that person unlawfully strangles, suffocates, or asphyxiates another person (B) to whom they are personally connected as defined in s 2 of this Act, where the strangulation, suffocation or asphyxiation does not result in B’s death’ (
16 June). This was rejected by the government, but
Baroness Newlove urged further consideration when the matter was debated in the House of Lords on 5 January 2021; and
Lord Lucas commended the NZ provision. After
debate on 3 February 2021, amendments proposed by Baroness Newlove did not proceed, but Clause 65 remains and the government promised further consideration.'
