And what are those you use regularly, those you use seldom and those you would like to experiment but just feel a bit too much?
I, technically, discovered sex toys still as a teen. I’ll leave the details for some other time. A bit embarrassing for the ocasion at hand.
I bought my first real sex toy when I was 18, which was a cock ring. Still my favourite kind of toy to this day. Have several. Then a pocket pussy. I still have a couple of these toys but I get too sensitive, so very seldom they get used.
With my partner I delved into anal play, so butt plugs, anal beads and dildos were added. I also own a cheap cock cage, that my partner does not enjoy me using. I use it occasionally just for my own personal fun.
The toy I’d like to experiment would be urethral sounds but the scare and risk factor overweighs the curiosity.

I’ve had involuntary electric stimulation in the course of a long series of physical therapy on my lower back. They warned me I could feel some unusual “side effects”. I didn’t orgasm. But it felt really good and left me with a serious erection that my partner had to “endure” with.
