Do you think this (not just the quote, but everything you've said about men and women) has something to do with the fact that, on average, men are more interested in things while women are more interested in people? It's a cliché, but there is plenty of research that corroborates it. If you grow up focusing on things, you learn to sort and categorize (and we do it to ourselves too, as you kinda pointed out). This isn't necessarily a bad thing. It can definitely be helpful in areas such as math and science. When it comes to porn games, this might translate to men wanting clear tags, fixed roles, repeatable steps, etc. People and relationships aren't parts to sort, though, since each one is unique and ever-changing. So, maybe, if you grow up focusing on relationships rather than things, you tend to develop a more open and fluid approach to the world (and sex).
Does any of this make sense?
