You forgot the part where he intimidated you into telling if you knew what a 'rubber' was. I remember being so fucking confused, because you always said 'condom' and at school they said 'condom', too.
The "don't do it" speech was followed by the, (at least for me) by the "but if I know you, you're gonna run right out and do it just to spite me, so use the rubber, knucklehead or we'll both be sorry, and if you have anymore questions don't bug me, go ask your brother." speech.
