Hi Koen, welcome to the site!
It's always okay to be content in Christ, single or not 😎. I always find the best matches when I'm not looking for one, but do as the Lord leads you!
As far as talking and introducing ourselves, start a thread asking a random question on a topic you find interesting and see what happens! This site is built more for conversations than connections, but many good connections have been made from the conversations. It just takes more time and patience than other platforms 🙂.
