Your first time buying Adult Diapers

I think my first time I was about 13-14, I had caught the train to the next town to buy them. I was vey nervous and ended getting the Depend with elstic straps for sides rather than proper nappy style ones. I had bought pullups and the like before and I was always always nervous.
There was another time when I was about 18 when the girl wjo served my was the girlfriend of a mate, luckily she did not recognise me.
