Say you meet a man/woman, date blah blah, one thing leads to another and you have sex. Whether you want to be extra careful or maybe there was error or maybe you were just stupid and didnt use protection, but now you want to get Plan b (~$50).

Who pays for it and why? Does this change in a stereotypical date (man pays for everything).

Edit: who are you people banging where you don’t trust them enough to take plan B without you being there
