That's interesting bear. Are you saying that a man who slept with you in that condition could have been genuinely mistaken about whether you were consenting?
I think it could have been possible, yes. I only had other people's word for my coherency - it was in the days before mobile phones and everything being recorded.
Because I think that's the rub here. I suspect you wouldn't have known yourself if you were genuinely consenting until afterwards. And rather than acknowledge that poor choices on your part was a contributing factor, you would be likely to decide you must have been raped. Not fair.
Ah, but I also know what I was like stone cold sober, and decisions I made then, too. So, while it could technically have been rape, in that I wasn't in a fit state to be able to consent, I think I would have probably said yes anyway, had I been sober, and also that anyone with me would probably have been able to have reasonable belief I was consenting, so it wouldn't have been rape. I never regretted any of them. But I completely recognise then and now that I was lucky - I was always with men I knew and fancied, and most times, they said no anyway. But I also realised that one day, I might not be so lucky, and also, I didn't like having a total blank in my memory, and I didn't want alcohol poisoning. So I stopped drinking so much. I actually made some far worse decisions about going to bed with certain men when totally sober. I don't consider that any of those occasions were rape. Remembering back mostly makes me smile, and in some cases, we're still in touch a quarter century or so later.
But - that is me. Not everyone reacts the same way to alcohol that I do. Other situations with other people could have very different outcomes.
In any case, it's not relevant, because drunk or sober, there is no reasonable way to believe that the woman in this case consented to sex with the mate of the bloke she had actually gone to bed with - she had consented to sex with the one she went to bed with only.
What is relevant is that I've met a lot of men who would make sure you get home safely and won't go to bed with a woman who is clearly drunk. Not all men are like this, which is why being anywhere with a man can be a risk - but if some men can behave this way, then all men are capable of it, and those who don't are choosing not to behave that way. Men are capable of better, regardless of how others around them behave.
