Why did he thank me after sex?

Guys typically have little, if any, respect for a woman willing to be a booty call. He may have been expressing this, putting you down in a way that reinforces his feelings of superiority but subtle enough to keep you coming back.

 

It's impossible for us to say with certainty because we aren't in your shoes and don't know your full relationship with this guy, so if you really suspect something is off, you should talk to him. If you get a vibe he is using you and trying to belittle you, cut him off. Why should you put up with someone who might not respect you?

 

You are getting paid for having sex with the person you want, without even having to ask for it.
This would be my dream come true.
Just fuckin take it and don´t regret it xD

 

I thought I would insert a smiley to imply that I was joking.

 

I think this is a question no one here can ever answer.

See communication via written words is very difficult (my misunderstood joke would be the perfect example for this). 60% of communication is body language, 35% vocal tonality and only 5% is what we actually say.
So only 5% of this whole story comes across to me.

But you are right leaving money after sex is something strange to do.
Thanking someone after sex is not. People tend to say the craziest things after sex. Take me for example, I sometimes say I love you. (I have an agreement with my gf that post sex "I love yous" don´t count, lol)

 

20 euros is not that much.
Either you weren't very good, he wasn't very happy or he was logical and legitimate in trying to help you out.
I mean this in the best sense, truly.
I'm being objective.

A thank you isn't a I love you.
Sex, to some cultures is a gift.
What nation is he from?

 

Also... Don't ask me how I know... But going rate for the cheapest hookers in the Red Light District is 60 euros.

 

Maybe he was a beginner and was thanking you for being so nice to him I know my first time I thanked the women I was with. Don't put too much into it he probably was just trying g to let you know he sincerely appreciated it I am sure he didn't mean to hurt you.

 

@green lion eating the sun
I think he was just being nice also.
I understand that as a woman it's our version of emasculating for this to happen and I'm sorry he hurt you.
I don't think he meant anything by it.
I think he was just trying to be polite to you and maybe try (not the best) to bridge possible cultural gaps?
At least that's how the story reads to me.
Best of luck with all your journeys moving forward

 

And what are you and what country are/were you in?
