Tipps for first time sex toy owners

Hi, I'm going to receive soon my first sex toys and I'm pretty excited. I bought a vibrator and a love ball thingy. I also bought lube and a toy cleaner.

Do you have any beginners tipps? What to try? What to do? What not to do? What to remember when using sex toys?...

I'm mostly interested in safety tipps and "bad ideas", but I will also be very happy for tipps on how to best enjoy my new toys
