After a trip into a wooded area, my parents needed to check my brother, sister and I for ticks. My father got in with us to search us head to toe (and actually found one on my sister). From this experience, I remember thinking that one day soon, my sister and I would start to grow our penises (as my brother and Dad both had them - and they were older). I literally thought that you had to be a certain age to have one, and it was only a matter of time before everyone got their own.
