There was no sex education when I was a boy. We suspected our penises had a function other than their obvious utilitarian purpose, but we knew not what it was. We discussed this behind the bike sheds (or, in fact, behind the urinal, which was situated at the far end of the playground, well away from the prying ears of our teachers). We all agreed our willies felt funny when we saw a nice-looking lady but we weren’t sure why. We all concluded it was a nice feeling, though.
