I had one of those glitter wands when I was young, and when I started experimenting (after trying a finger first) I used it a lot. I remember being a little sore the first few times I tried, but it felt pretty good, so I kept doing it. I didn't realise it at the time, but it made me squirt neerly every time, I was just too clumsy and inexperienced for it to feel anything like how people described orgasms. It took years to figure out vaginal orgasms aren't very strong for me until I've had a few, so back then I was probably accidentally ruining the weak orgasms I would have had if I knew what I was doing.
Then one day my parents got a new shower head and I spent the next 2 years taking 60+ minute showers because I discovered clitoral orgasms.
The first real sex toy I got came in a set. I bought them when I was 16 and they were all hard plastic toys, including a vibrator, bullet vibrator, and egg vibrator. The bullet wasn't strong enough and it took a long time with the regular vibrator, but it was nice to have options beside the shower because using my hands wasn't working.
The first anal toy I got was a set of butt plugs, but I didn't use them very often. It took several years before I really got into anal and by that time I had learned about safe and unsafe materials, so I had to replace them with new ones.
