'...recent survey by the government-funded charity the Institute For Addressing Strangulation, external (IFAS), suggests strangling is most common in the 16-34 age group, with 35% of respondents reporting they had been choked by a partner during consensual sex.
Some 16% of all UK-based respondents (385 out of 2,344) have been strangled once or more during consensual sex, and the data shows a slightly higher proportion of women have experienced it compared with men.
Half of the sample who had experienced it said they had agreed to it, while 17% said they hadn't.'
