How conservative the Japanese people really is? And the government?

They were very similar to the bromance of today but accompanied by sexual intercourse.

In the old era, gay relationships were very common and were even praised among the privileged social classes, such as Samurai and monks.

This is a very vague question. But considering the asker’s comment on Mr. Nakajima’s answer, your interest seems to be in sex-related matters (I don’t think it’s the only indicator of conservative/ progressive, though).

Why do nice guys rarely or never win?

I sometimes feel people from the West are obsessed with those “gender” and “sex” things too much. Let’s think about something else sometimes. It’s unhealthy.

Yaoi

“None of my business” is the common attitude.

What if you were the only and last person left on Earth. How will you survive and what would you do with your life?

How do you see these below?

It’s very common for a girl/ woman to ask a boy/ man to be her boyfriend.

They don’t have the value that “guys must be macho.”

How do you get started in bestiality with a dog as a male?

They don’t bring around their mates everywhere, which means they don’t worry about being single, gay, or whatever because no one cares about whom others are having/ not having sex with.

They don’t have the so-called “couple culture” seen in many Western countries.

We don’t instantly tie it with sex when a father and his very young daughter are taking a bath together.

Why isn't bestiality illegal in most states? If children can't consent, then animals DEFINITELY can't consent. Why is being a pedophile a crime but zoophilia is not?

They don’t tease or beat up cross-dressed people on the road.

Moreover, buff guys are often avoided for their narcissism.

Visual-kei

Why do men first look at a woman's chest instead of their face?

I’ve heard it’s always the male side that is expected to take a move in some countries. It’s not the case in Japan.
