I was 13, and I had discovered the joys of masturbation. And like many boys who experience this epiphany, I got rather addicted to the activity. At one point, not long after experiencing my first ejaculation, there seemed barely an hour when I wasn’t either thinking about wanking, or actually doing it.
My head was ruled by my dick even during school hours. I went to quite a traditional Catholic grammar school in the late 50s, where the cane was in regular and painful use.
