A skeleton was found in Czech Republic and dated back between 2900 and 2500 BC, this turned out to be one of the most interesting and most looked at skeletons to date. Not because of the grave goods, or where he was found, no it was because he was discovered to be "gay" by the way he was buried.
The skeleton was found pointing to the east with many domestic jugs, such burial practices were only found to be related to females before this man was found which made everyone jump to the conclusion that he must be gay (looking at gender and sex)
Sex is looked at biologically but gender is looked at culturally, this is how they assume that he is male based on the skeleton but his gender would be feminine because of the way he was buried. Men in this period were generally buried on their right side with head to the west, women were on their left with heads to the east which is how this man was found. Rather than being buried with weapons like other men, he was buried with jugs which also relates to females.
I'm not sure if i would jump to the assumption that he was gay, maybe he wasn't even a he. Many skeletons found have to have a slight guess as to which gender they are so maybe this skeleton was a girl, or maybe he was gay. I guess we will never really know what this skeleton was, everyone will just assume what they want to.
