A man visits a sexuologist and says: "Doctor, every time after I [have a good time with my wife], three flies fly out of her nose." The sexuologist has obviously never heard of anything like that. So he visits the man at home, and gets to observe the couple to [have a good time]. And, indeed, after everything is over, three flies fly out of the wife's nose. That, naturally, spurs his curiosity to the extreme. So, he decides to examine the man and the woman. After he is done, he turns to the man, and says: "OK, I finally know what your problem is!"Spoiler:"Your wife has been dead for three months."
Also, I want to be a sexuologist when I grow up.
