Welcome Wooki!
It'll take a while to get the fit of your bike right for you.
Saddle, saddle position, grips, and maybe even gearing later on.
Step one: Enjoy the ride.
You probably don't look silly.
You might even get questions about your bike.
Folding bikes are inherently cool
and if someone doesn't think so, the you don't need that negativity in your life.
Stick with the fold.
