I ([M]19) fucked a couchsurfer ([W]20)during her stay in Berlin

This story happens a few years ago but I feel like I finally have to share it now. I’m not a native speaker, sorry for some grammatical mistakes.

That time I lived together with my girlfriend until she left me and moved out. She was my first relationship and the only person I had sex with. After her departure I felt pretty lonely because we haven’t lived in Berlin for a long time and I didn’t find a lot of new friends. So I came up with the idea to check Couchsurfing if anybody needs a place to sleep. In my opinion it was a win-win-situation, the person could sleep on my couch for free and I would have some company.

A few days passed till Anna (not her real name) wrote me and asked if she could spend a few nights on my couch. Of course I stalked Anna on Social Media before, you have to know on Couchsurfing are some weirdos.
She was only one year older than me and just made a world trip with some days residence in the capital of Germany. On her photos I could see she had a boyfriend so I’ve thought nothing further and was happy to hear some stories she had experienced in other countries.
