is it normal for a 17 year old girl to talk to 40 and 59 year old men

I think its ok for teens to talk to older adults as well.
(The point about the nudes is obviously breaking laws. But chatting is fine).
I had an older girlfriend once who had a very young sister, we chatted for years, and now that she's 21 we are still close friends, I could message her right now if I wanted to, and both of us are happy and safe :)
The present world has made people so jumpy now, when the irony is that there is no difference to the past, older guys STILL talked to younger girls 30 years ago, but these days that's counted as a monster!

At what age is it for a guy, when they can NEVER ever have another conversation with an under 18yo? All these young guys here must be thinking, oh yeah can't talk to under 18yo ever again after 25 Lol, oh unless we have our own kids, BUT after that GONE!
