You are correct, but the idea of carrying one where people can see one shows responsibility that you have more in a drawer (Like you say).
So, I thank you for that and I hope our ideas combine.
I simply doubt that some one showing a condom wouldn't use that one and would (For our sake) know to use a proper one in a proper place.
Wouldn't it be funny if they tried using it in public after showing it off! Ha! They'd get caught on "Guys Gone Wild".
I am personally abstanent so, we can add your idea to mine and add a warning label on the key chain for the ladies....
No harm done adding more info too a good idea.
