I think guys are becoming insecure nowadays
Insecure in what way?
I don't know if I'd call it "insecure", but I have learned to always keep myself safe. And yes, I do realize that, if I'm assaulted or my house is broken into, odds are it will be a man who commits the crime. And some men seem to have all sorts of bizarre ideas about women and little or no respect for us or our boundaries. That's just the way of it. The thing is just to keep your wits about you, and remember that words are cheap, and that there is nothing more important than keeping yourself safe.
Sometimes not trusting is a very wise thing to do.
