Had op said stop and he carried on then it was absolutely rape, no question and she’d have a definitive answer.
Beentherefonethat I believe you are wrong. Very, very wrong.
I was forcibly gang-raped at fifteen. It was horrific, humiliating situation in which the youths concerned mocked and jeered at me, making out I was some kind of freak, so that by the time they'd finished with me all I was afraid of was that anyone else would find out and could join in that mockery. THEY should have been the ones who feared others finding out! The fact that I'd internalised that so effectively is something that amazes me even now.
What I don't do is assume that others' experiences of rape - and I'm terribly sorry this has happened to you too - are going to be an exact match for mine. There's no doubt but that to be held down and have enforced obscenities inflicted on you, as I did, is indeed rape. But that doesn't make other instances of this crime any less clear-cut or the lines between consent and 'not-consent' any murkier.
The yardstick - legally I believe - is 'enthusiastic consent'. Your definition seems to be that to qualify as rape a sexual act has to go against an outright utterance of the word 'no', and that any other aggravating factors do not matter. That just isn't the case, and I doubt there could be any stronger indication AGAINST enthusiastic consent than an unwilling partner physically fighting you or pushing you off. This can be looked up online if need be, but the waters here are not as muddy as some of your posts above tend to suggest.
I also understand where the OP must be coming from in this situation. I've spoken to other rape victims and also seen them post on Mumsnet. Many are not sure in the first instance as to whether what they suffered was actual rape. More, when it related to a partner they had loved and cared for, understandably didn't want to accept that it was rape and went through a very unpleasant process indeed - sometimes a slow and painful one - along the road to recognition of that fact. Of course they don't want to believe their partners capable of such an atrocity, and they internalise that shame upon themselves.
The incident described in the OP aboves was unambiguously rape. I'm sorry - there are no murky waters, no blurred boundaries, no distinctions. Anything short of enthusiastic consent is rape.
This on its own will be a hell of a lot for the OP to process. But questioning whether or not what she experienced was rape seems to be downplaying the seriousness and enormity of what's happened here. I don't believe that's helpful for her at all.
To the OP, your only call right now is to look after yourself. You don't have to report it. (I was told that if I didn't do so, if my rapists did this again it would by MY fault. It wouldn't. The only people who bear culpability are the rapists). You don't have to tell your family. You don't have to do one single thing you don't want to do.
I do, though, suggest you get help and support in coming to terms with what's happened. Rape crisis could be beneficial here. Take your time, take care of you, and allow yourself chance to process it. After that, whichever course of action you take is up to you. There are sometimes very good reasons why women don't report, and having been one of them I'd never stand in judgement of any one of them because of it.
Take care of yourself
