I think that's a really good idea. Even in the wrapper, condoms can degrade when kicking around in someone's pocket for too long. Keys, coins etc can wear holes in the wrapper (and contents!) which is just not safe.
Heather, you could buy some felt and embroidery cotton now, begin sewing now so you can give one each to your kids (filled, of course). Not only will your kids be safe, but getting a gift like this from their mother would really put a crimp in any of their plans to become sexually active.
About the time AIDS awareness was beginning to turn from scare-mongering to sensible, I remember my very trendy sister (also very married sister) wearing a gold antique-looking case around her neck. It looked like it could contain a small pair of those old-fashioned gold-rimmed specs, made up as reading glasses. I asked her what the case was, she said it was a condom case. She wasn't carrying any in her case, she didn't need them, but liked the old-fashioned appearance and the gold. By the look of it, hers would have held two condoms, side by side.
Some years ago (a year before I had difficult child 3) husband & I were wandering around Sydney, in Oxford St (think - Soho). It's that part of Sydney which lit up pink and rainbow last night for the Gay & Lesbian Mardi Gras. One very fashionable shop was very enjoyable to browse (but expensive!). I noticed some round silver discs at the counter, apparently to be worn as pendants. When I asked what they were the young man behind the counter squirmed, I think he was embarrassed to have an older, female, person ask. "It's for carrying a condom in," he finally showed me. "You can flip the case open like this. That way you won't be caught without, you will be able to be safe and ensure your partner is safe." He glanced at husband - both men now beginning to look embarrassed.
Then I REALLY put my foot in it. Thinking of my sister's case for two condoms, I said, "But what if you want more than one condom with you? What if you want to carry a few more?"
husband dragged me out of the store. "What does it say about you," he explained, "to be wanting to carry multiple condoms on ONE night out? And what does it say about me, that you felt you had to ask that question?"
I got the point.
