I tend to fall most of the time in the middle. It can be as situational, or non-situational as is necessary or required. And a lot of the time, people will express certain aspects of these things at certain times, and the other aspects at other times. Just as there are aggressive women and submissive men in het relationships, there can be aggressive fem guys and submissive masc guys. Gay relationships, at least in my experience, are a lot more similar to straight relationships than most people would realize. Let me preface my answer by saying I can only speak to my own experience and I don't want to imply that I speak for everyone. Does this mean that generally speaking, there has to be masculinity and femininity in a relationship for it to be successful? For the most part, I have seen gay couples whose partners are the opposite of them. Can a gay relationship be successful if both partners are feminine or both masculine? This is coming from a straight man with very little knowledge about why some gay men act feminine and flamboyant and why some gay women can be masculine and stern.
