This isn't 'guy' behaviour, it is, to use a colloquialism, knobhead behaviour. The kids in the audience who actually wanted to learn something interesting about science weren't wolf-whistling. The people who are perpetuating that kind of behaviour are idiots with a stupid, narrow view of what it means to be male. These are the same people who will use 'geek' as an insult and think that if you don't conform to their idea of how to behave that you're not a 'proper' man. For the love of god I have no idea why you're trying to suggest that they might be right.
