Women are having sex with shapeshifters/demons/aliens during the night
I asked average women how many men they fucked in their lives: the average is 50. I asked men: the average is 5 women. But for every sex between man and woman, you need one of each, which means the average should be the same for both sexes.
The only explanation I have for this phenomena is that women are having sex with creatures that LOOK like men, but aren't. Creatures that appear at the night, fuck women and they never hear about them again. There are a lot of creatures like that in mythology and folklore: shapeshifters, doppelgangers, reptilians, incubus, etc. They are probably fucking women and inserting their DNA in them through microchimerism/telegony or even impregnating them. They are slowly changing human DNA through sex with women. They probably control the government and media as well and that's why there's so much push for promiscuity.
99% of women will lie about this if you ask them but secretly all women are fucking strange interdimensional creatures every single night.
