I'm an old man.
So, believe me when I say you just need to put yourself out there, in social spaces, and meet girls/boys face to face, and just be yourself. Don't put on a false face, a "front." Just be you.
It helps to go to places, or events, that coincide with your personality type.
Don't give up, don't take every rejection as a death sentence.
You can do this.
No joke, I have a very close friend who is a vagabond. It the most literal sense of the word. He has no permanent residence.
I love the guy, he's a great friend, loyal, dependable, trustworthy.
But, I've heard that people have found objects beneath the couch he crashed on with... certain matter on it.
Hey, I'm not judging, but at least you could take that with you, or wash it off.
