Sure, Assume that there are twice as many men in this room, then if a sexual remark is made by a random person, then it will twice as often be made by a male. If the target of said sexual remark is always of the opposite sex, then a specific sexual remark made against a male will have twice as many males to choose from, meaning that a particular male has half the chance of receiving each comment than a female would.

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.
