LOL...how many different ways are there to use a condom? I have never seen the banana demonstration but figured it out all on my own in about 5 seconds. Maybe I am just that much smarter than everyone else....but it sounds like an excuse for a stronger nanny state to take care of us.
Are you being intentionally obtuse? If not, your comment about your own smarts needs revisiting.
Do the instructions say when to put it on? Many use the condom only when, uh, the moment is nigh, if you know what I mean. Of course, seminal fluid is potentially released prior to that happy ending.
How 'bout taking it off after it said happy ending? Quite the potential for error there as well.
And 16 year old kids are certainly well known for their attention to detail.
