I can remember getting a hard-on from age 12, or maybe even earlier. I always knew that it happened, but I suppose even then it was something so private that it never got discussed with my parents or anyone else. My friend’s older brother exclaimed “my wiener’s stiff”. I knew instantly what he meant, and I realized that my prepubescent erections were shared by others. I never had really noticed that it had grown in the last few months. When a friend shared his experienced things throughout puberty. For instance, he’d write the date and age when he first started getting facial hair or when he first started getting pubic hair. So, I would have loved to have like taken a picture every day or week from like 12 years old to see how much I changed. Because most changes are very slow of course, It would’ve been great to look back and see how much I’ve changed. I just think it’s a good way to keep a timeline. Does anyone else do this?
