My one (mild) complaint about the original post is that it mentions these sorts of fantasies being common among both men and women, but only cites data about women. So I did a little googling, and although this wasn’t published when OP first made this post (and thus can’t be blamed for not including it), I did find this great article, from a social psychologist who reports on a survey he did of 4000 Americans aged 18-87 (not just college aged women). He found that (exact quotes from the article):
“61% of self-identified women had fantasized about this [being forced to have sex] before, while 24% said they fantasized about it often.”
“54% of self-identified men had fantasized about this before, while 11.5% said they fantasized about it often.”
“68% of non-binary participants had fantasized about this before, while 31% said they fantasized about it often.”
Interestingly, the same guy also asked people about the inverse, i.e. did they fantasize about forcing sex on someone else, which he talks about in a blog post. He found (again using exact quotes):
“20% of self-identified women had fantasized about this [forcing sex on someone else] before, while 4% said they fantasized about it often”
“38% of self-identified men had fantasized about this before, while 7% said they fantasized about it often”
“38% of non-binary participants had fantasized about this before, while 9% said they fantasized about it often”
I recommend reading both articles, they go into a lot more detail than I’ve reported here. This guy also wrote a book on this topic, though I haven’t read it.
TLDR: you’re not a freak or abnormal, there is no such thing as thoughtcrime.
