Well, yeah! No one likes to wear helmets. They're uncomfortable and bulky, it's awkward putting them on when you're in the mood to skate, sometimes you don't have one handy when you need it, and it lessens the feeling of the breeze in your hair. So, can you blame a fellow if he doesn't always wear one of those things?
But condoms — well, who doesn't like the feeling of those? Hardly seems worthwhile to do "that" if you're not wearing a nice snug condom to enhance that feeling intimacy.
