The "probably" part is definitely a "just-so" story. It is unfalsifiable. As for the hypothesis that the revulsion is instinctive, well, the only other possibility is that it is learned. But if its learned, then this conversation wouldn't be happening in the first place. It wouldn't be a big deal. The only reason this conversation is even capable of happening is because everyone already implicitly believes that women and only women are instinctively repulsed by direct or subtle sexuality that isn't pre-approved, that is, it is a violation of their core values and therefore we have a problem to be solved.

If men will admit to themselves what they already know and believe, they will be better prepared to handle themselves to avoid conflict with their female counterparts.
