I think exactly this is the reason why many mans perceive the sexual harassment and the sexist argument has overkill sometimes, basically it's an issue cause by a low exposure to it.
Thank you for this comment, i'll use it as an argument in sexism discussions trying to help other fellow mans to understand it.

Word of caution though, I may be misremembering the model and may be totally off base. I couldn't find the reference very easily, so if you'd like to use this argument yourself, try running a similar model through Excel/Python/R first. It'll give you a pretty good idea of the issues involved.
Happy coding and empathizing!
On the other hand, it's my experience that women are far more likely to share obnoxious comments with their friends. But I admit that's based on a small sample, just close female friends and lovers, and wives. And perhaps I'm not the sort of guy who encourages such sharing by male friends. Or even has such male friends, for that matter.
So as a summary: if there are twice as many males in the room and everyone is equally likely to make a sexual comment against the opposite sex, then females would get 4 such comments for each comment a male gets.
Now, for normal everyday examples like walking down the street, asking a question in a class, taking the train, etc.. Does it seem likely to be twice as many males in this "room"?
https://en.wikipedia.org/wiki/Human_sex_ratio says that there are 1.01 males to each female, I would say that this is not nearly enough to account for this difference.
There is a stats model as to why this is. I can't find the reference, so my recollection may be spotty.
Essentially, assume there are more men than women in some room. Assume that some percent of either sex will espouse sexist comments at the other sex. Running through the math, you find that women hear more sexist comments than men do. If you plug in some real world numbers (of sex imbalances, sexist remark frequencies, time in various environments, etc) to these percentages and not just some random ones, then something like 95% of women will get some very crude remarks thrown their way nearly every day. Again, I can't find the reference, but it has it's own eponymously named rule to it on Wikipedia (though it's not on that linking page yet for some reason).
Basically, one possible reason men don't hear a lot of very sexist stuff all that time is 'because math'. Men need to listen to their sisters, mothers, wives, friends, and coworkers and believe them more often.
