A saying or feeling that you get when you did something wrong that hurt you or other, or you we're suppose to do, but received pleasure in the from of sex.
In the end, you got fucked and nothing else mattered
The movie Avatar:
"Betray the entire human race? Doesn't matter had sex!"
I Just Had Sex(song):
"She kept looking at her watch. Doesn’t matter had sex.
But I cried the whole time. Doesn’t matter had sex.
I think she might have been a racist. Doesn’t matter had sex.
She put a bag on my head. Still counts."
