Yes I suspect it is.
There's a lot of emotion bound up with this, isn't there? Sexist men tell women that what we say about rape is not valid because we get too emotional about it, because we're too invested in it - particularly if we have disclosed that we have been raped.
But people are very unwilling to confront male emotion about rape; that determination to not recognise it when it happens, that unwillingness to call another man a rapist unless it is 100% certain that he is one because a court of law has convicted him (and even then many men are unwilling to accept that verdict). Lots of men don't like the word "rapey" because it's too close to rape and it's an incredibly useful term because it points to an attitude that they don't want women to call them on. There is an enormous taboo about pointing out when men are talking like a rapist or acting like a rapist, it would be considered deeply shocking to casually say something like "Oh, I'm sure x is a rapist, he talks exactly like one and his attitudes are indistinguishable from one, so I always assume he's one and won't stay late in the office with him, just in case". Can you imagine the horror if women spoke about rape in those terms?
I've sat round the table with friends (male) who have said "well you can't say he's a rapist because he wasn't convicted" and I've said "yes you can, he's a rapist, he raped that girl and he wasn't convicted because the law's been set up to let him get away with it and yeah, if you were on a jury you might have to give him the benefit of the doubt because there may be reasonable doubt, but we here, sitting round this table, chatting about it, we don't have to give him the benefit of the doubt, we're not in a law court are we? We can use our knowledge and our perceptions and our judgement and decide whether we think he's a rapist and if we think he is why shouldn't we call him one? He's not going to be hurt by it, he doesn't know us, it's not a public forum, it's a private party, why can't we call him a rapist?" and they've been stunned by it.
And I reckon that "men need sex" thing is part and parcel of that - must acknowledge men's "sexual needs" but not so needy as to be a rapist because rapist = bad while sexual needs = good and right and reasonable. So the rapist has to be separated from the normal men with reasonable needs.
