Make a DNA test with a company of your choice. I do personally guarantee you have a double digit percentage of Neanderthal dna. Nobody wants unsolicited dick pics and if that's not super obvious to a person, they need at least a couple of OS updates, but probably even new firmware.
Maybe, just maybe dick pics get sent more often to females who sort of show more awareness to the fact they are sexual beings than others. Doesn't make it the tiniest bit better
