Weird but true fact - its actually quite common for people to have sexual thoughts about family members; they usually occur when the person is young and has not yet developed a robust social network. Obv in today's modern American society it's considered completely sick to act on such urges, but in plenty of earlier cultures and still in some parts of the world today, that is not the case. All that said, LOL at Mike for posting that. You never cease to surprise.
