I simply think a lot of men don't understand, that the trauma is worse.
The do get that it's painful and can also be very physically damaging, and still, i think i wrote about this on lolcow before:
My younger brother is a nice normal dude, but we still had a fight over him saying that being falsely accused of rape is mentally more damaging than the actual rape itself.
If you read some rape reports; one woman i think it was in Sweden being gang raped by refugees there at some times 3 of them were inside her - how could she ever trust any men again? Sometimes even the skin between vagina and anus rips, that's not something anybody can ever get over with. I'd go as far as to say that rape is somehow even worse than murder; it not only affects the victim, but also every single person they know, their future life, tge husband or children she may never have, because it's something that will torture her for the rest of her life.
A few months ago there was even this thread about a rape victim being allowed to commit assisted suicide
