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

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).

Moreover, buff guys are often avoided for their narcissism.

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

Why in my 60s do I have a strong desire to suck cock and swallow?

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

Visual-kei

How do you see these below?

Why didn't my ex fight for our relationship? He gave up so easily.

Yaoi

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

“None of my business” is the common attitude.

I have the power to talk to aliens through using telepathy. Why do people think I'm crazy?

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

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.

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

Why does my narcissistic ex told me that he f*cked and sleep with other woman and then at the end says that it also happened because of me?

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

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.

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.

What is it like to have an insanely beautiful girlfriend?

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