Men's disposable panties

I was in Japan's $5 shop and I saw this:

Men's disposable panties


We're just a heart beat away
One touch could make it happen
We can reach the other side
If we hold on to the passion


I was like,

"Hmmmmmm is this some kind of instruction or what?"

"Is this a description of male mast***ation?" 

"Is this why the men need to have disposable panties?"
