Guys, Why do men protect women?

Anonymous
Usually I know why it happens. Just yesterday I wanted to remember old time and played one of the online fighting game. When guys in this online game saw that I was a woman, they started behaving in other way. One guy fighter came to me told me that I was no good at playing and he would help me to win, that he would protect me. And his aim of playing became to stay me alive (in game). Then i guessed that It doesn't only happen in reality but in online games too. And I am interested why do they try to protect you even in the game when they should play for their enjoyment and not for a strange woman?
