friendsters’ behavior

I have been restarting my friendster account of late and to my surprise, most of those I have invited are males. However, those that accept me as a friend are mostly female. I think there shouldn’t be any chemistry because things are done over the internet, you are facing a computer and not a real person. However, if male would not add other male that easily fearing that their list of girls are exposed to their competitors. And most male are paranoid by hiding their profile while girls are more open towards who are their friends.
