Western civilization:

A guy would need a really good reason to cry in front of others, but it's totally fine to cry if you're locked up in a room all alone. It's also fine to be sad in a dry way in front of others. This is what people think anyway. Weird, but it's how it works.

As for me, I haven't cried since I was 12. That doesn't mean I haven't been sad, though. I've been sad a lot of times, but I did not cry. It's not like I hold the tears back either, there's just nothing to hold back. I guess I'm not so emotional, at least not in the sad department.
