How do you manage condoms? Just carry one in your wallet at all times or what?

What do you think if a girl has a condom? Full disclosure, I had an abortion three years ago and since then I keep condoms in my room and car. Have I ever even used them with a hook up? No, but I don't want a repeat. Even in a relationship I double up with condoms and birth control. So is this just a societal consensus of a double standard you subscribe to because if a girl plans ahead it signals she's slutty, or what's your take on it?

And to any guys that "just don't do condoms"...ew. Just ew.
