I wouldn't call it sexism. When I was maybe 10, I was friends with another kid (a boy, like myself) just because he had a nintendo. Most people (my adult self included) would condemn that behavior in much the same way, particularly coming from an adult.
If you'd condemn a man behaving the same way (e.g., making friends in order to use a playstation), it isn't sexism.
