“I remember bits of it – like being smacked so hard around the head that everything went white and I couldn’t see.
“I was there for maybe six hours in total and the only reason they let me out, in the end, was that they had work to do.
“So I went home, then passed out for a bit, and when I woke up I went to A&E.”
Despite the violence, it wasn’t until later that Sali started to consider what had happened as rape.
“Bisexuality is seen by a lot of people as just a type of porn with two women and one man and that definitely influenced what happened to me.”
Sali says she didn’t go to the police because she feels she wouldn’t have been successful in court.
Only around 2% of reported rapes in England and Wales result in a conviction. “Although I fully support people who do go to the police about sexual violence… bi women are seen as greedy, slutty, asking for it.
“So if I’d even had got as far as it having made it to the court which wouldn’t happen anyway because it would’ve been dropped long before that – there’s no way I’d win.”
Geri Burnikell, from the rape charity SupportLine, said she would encourage all victims of rape to report it to police.
She added: “We fully understand that some are reluctant to do so due to the low conviction rates which mean many perpetrators get away with what they have done.”
