I think you missed the point again.If we can shape our attraction for feminine and masculine traits, then we can decide to be straight.
We're talking about the social characteristics that are actually not inherent to men and women. Eg, a man may express himself with a lot of mannerisms, but that's how he is.
In this case there's a peculiar social flexibility given to women, because they're allowed to express themselves more emotionally than men. If men had menopause, they wouldn't be allowed to show it, because of the ingrained boys-don't-cry mentality. Even as awful as it may be, it would be expected of men to remain stoic.Hormones make quite an impact on behavior. I'm pretty sure females being particularly sensitive during menopause is not related to society one bit. This is just an example, men have higher testosterone levels, so differences in personality do exist.
So even though our bodies may be producing different hormones, our roles and what we're allowed to exhibit are still very different. Not because of the hormones, but because of the rules that go with being a man or a woman.
