Hi. I'm 23m, and I want to start dating. I've never been in a relationship before.

Up to recently, I didn't try dating because my father wouldn't approve of me being with a guy. I moved to another country and one part of me wants to start dating, but the other is very anxious about it.

I think things like:
What if I date someone and it is super awkward?
What would I do if I didn't like a date and don't want to keep in contact? How could I tell the other person?
What if he thinks my hobbies/music tastes/etc. are lame?
What if we don't have enough things in common?
What if I find him way less attractive in person?
What will I do when I eventually have to tell my family that I'm in a relationship?

So many things and more make me stressed out and I end up ignoring my matches on dating apps. 

What advice would you give me?
