Need to know what can i do with newly bought toys and what happens with them

Hi❤️,
Im in a chastity and i needed to bought some toys to play with as i wanted to stop boring traditional jerking off get in to tease and denial or frustration training.

So, i brought a hitachi like vibrator and a curvy beeded toy which is glass.

I heard prostate milking, and i didn't tried it with a toy and never had a release from it when using fingers and its really hard to do with fingers and want to experience that with a toy how can i achieve it?

What can i do with the vibrator or combine both of them and play any advices or experiences?
