Posting under what is certainly a throwaway account to avoid recognition if he ends up choosing witness protection, Reddit user Throwthricethree shared a tale in the infamous subreddit "Today I Fucked Up." His post's title, of course, says it all.
In a close reading of the text, you'll notice that this is not the first time Throwthricethree has mentioned his peculiar mental hang-up to his wife. The first time, she assured him the hygienic practice did not hurt.
That could have been the end. He could have accepted that. He could have moved on with his life, could have looked away or chosen to take up a hobby—like watching TV, Downton Abbey is particularly engaging—whenever his wife came out of the shower.
Instead, he let the thought fester. Even tried to justify it with some sort of disgusting smegma analogy. Until at long last his dark misgivings bubbled to the top of his subconscious and he convinced himself it would be OK to let them loose. It was not OK. The response in the comments summed up as much, primarily centering on the idea that, "If you don't know where you fucked up, you're pretty dumb."
Someecards has reached out for comment and to find out how and if the situation was resolved, but hasn't heard anything yet. Hopefully, Throwthricethree will manage to clean up the situation in a way his wife doesn't find physically repugnant.
