I've been using BTC for a while. I've been using it at exchanges, to trade altcoins and to order goods over the Internet, but I've never exchanged BTC with someone in front of me. At a store or between friends, or family. This despite having had long conversations about BTC with various kinds of people, and attending a few meetups.
Who has exchanged BTC F2F?
It is actually you are exchanging your bitcoin on exchanges conveniently without any hurdle that is why you are happy with your process of exchanging your bitcoin with fiat and have not talked to anyone for changing it face to face. When you will face any hurdle doing it on exchanges then you will start to ask from your community around you for the exchange then you will find many of them and will experience that process.
