As someone incontinent from birth, with both parents working full-time, my memories are understandably less traumatic than yours. I had endless babysitters as a child, but it all came to a halt when I was 11 and entering puberty with a bang. Rhona, my last sitter, was 13 at the time, and as fascinated by my erections as I was with her breasts. She jacked me off many times while I was nursing on her tits, though my orgasms remained dry until I was 13.
I lost my virginity at 16 (11th grade), and had a long string of sexual encounters in college. I've always been open about wearing diapers, and at UCLA in the mid-60's there were plenty of girls who enjoyed a bit of kink to go with the drugs and rock n roll. From my point of view, at 13 Tom should pray for a babysitter like the girl at the store; you never know where a diaper change might lead.
I didn't know these existed. Mattresses designed for bedwetters. I like it! Also bedbug, etc pest-proof is an added bonus. Heck I could see non-bedwetters buying these just for the bedbug protection. Awesome!
I'm mainly a Windows user. The only time I've ever used a Mac was for about a year when my uncle gave one to my parents when I was about 6. However, I didn't start using it until I was about 7. I already missed using Windows because some of my favorite computer games to play were incompatible with Macs at the time.
