What do you do with your used condoms after hooking up at her place?

I was thinking about this while carrying my used condom with me on my way out of a recent hookup’s apartment.

When I was BP, I would just leave my condom on girls’ floors no fucks given. But now I’m a little more paranoid about where I leave my DNA laying around. You can’t flush it, and I don’t even trust it in her trash can. You just never know with people these days.

Do you have anything specific you do with your condoms after you hook up with a girl at her place? Am I the only one that takes it with me and throws it in a trash can outside?
