People are being a bit overly literal here IMO.
I'm sure you could find 100 women who would be up for this if you searched far and wide, as there are a huge number of women in the world and some people are strange!
But that's not the point.
OP, may I suggest what you're really asking (i.e. common sense says!) if it would be dead easy to find 100 women to fuck the same man in a day, as easy as it would be to find 100 men?
And the answer to that is - of course not, it would be much harder to find women to do this. Most women wouldn't want to. Would most men? Possibly
Last time I looked, there were 13.5 million men locked up for sex crimes in England and Wales. But only 130 in women's prisons for sex crime (some of whom were actually men)
That's the scale of the difference.
That translates to something like one in every 2,500 men in our society currently locked for a sex crime, compared to 1 in every 230,000 women (or fewer if some of them are really men).
Given how rare it is for sex crimes to be reported and then again rare to actually be convicted, that's a lot of men guilty of sex crime walking around in society.
Depressing AF.
