Durex Gossamer has a special place in my heart as I used one of these when I has sex for the very first time.
They bring back memories of me trembling trying to get the money together at the till in Boots, hoping there were none of our teachers in the queue behind me, girlfriend waiting outside and then off to her place while her mum and dad were safely in Tesco's or wherever!
Anyway they did the job and we stayed together till we went off to separate colleges! Since then I've used them whenever I just needed a dependable condom and didn't know whether or not the girl might like anything more exciting like ribbed etc, or whether she might be sensitive to spermicide.
I have found sometimes that the lubricant can dry up rather quickly so this can be a problem if the girl isn't particularly well lubricated naturally, so some extra lube might be useful.
